ICL3221E, ICL3222E, ICL3223E, ICL3232E, ICL3241E, ICL3243E
±15kV ESD Protected, +3V to +5.5V, 1µA, 250kbps, RS-232 Transmitters/Receivers
The ICL3221E, ICL3222E, ICL3223E, ICL3232E,
ICL3241E, and ICL3243E are 3.0V to 5.5V powered
RS-232 transmitters/receivers that meet ElA/TIA-232
and V.28/V.24 specifications, even at VCC = 3.0V.
Additionally, they provide ±15kV ESD protection
(IEC61000-4-2 Air Gap and Human Body Model) on
transmitter outputs and receiver inputs (RS-232 pins).
Targeted applications are notebook and laptop
computers in which the low operational power
consumption and even lower standby power
consumption is critical. Efficient on-chip charge
pumps, coupled with manual and automatic
power-down functions (except for the ICL3232E),
reduce the standby supply current to a 1µA trickle.
Small footprint packaging and the use of small, low
value capacitors ensure board space savings. Data
rates greater than 250kbps are ensured at worst case
load conditions. This family is fully compatible with
3.3V-only systems, mixed 3.3V and 5.0V systems,
and 5.0V-only systems.
Features
• ESD protection for RS-232 I/O pins to ±15kV
(IEC61000)
• Drop-in replacements for the MAX3221E,
MAX3222E, MAX3223E, MAX3232E, MAX3241E,
MAX3243E, and SP3243E
• The ICL3221E is a low-power, pin-compatible
upgrade for the 5V MAX221E
• The ICL3222E is a low-power, pin-compatible
upgrade for the 5V MAX242E and SP312E
• The ICL3232E is a low-power upgrade for the
HIN232E, ICL232, and pin-compatible competitor
devices
• RS-232 compatible with VCC = 2.7V
• Meets EIA/TIA-232 and V.28/V.24 specifications
at 3V
• Latch-up free
The ICL324XE are 3-driver, 5-receiver devices that
provide a complete serial port suitable for laptop or
notebook computers. Both devices also include
noninverting always-active receivers for “wake-up”
capability.
• On-chip voltage converters require only four
external 0.1µF capacitors at VCC = 3.3V
The ICL3221E, ICL3223E, and ICL3243E feature an
automatic power-down function that powers down the
on-chip power supply and driver circuits. Power-down
occurs when an attached peripheral device is shut off
or the RS-232 cable is removed, which conserves
system power automatically without changes to the
hardware or operating system. These devices power
up again when a valid RS-232 voltage is applied to
any receiver input.
• Receiver hysteresis for improved noise immunity
Table 1 on page 2 summarizes the features of the
devices represented by this datasheet, and
Application Note AN9863 summarizes the features of
each device in the ICL32xxE 3V family.

4. Application Information
Application Information
The ICL32xxE interface ICs operate from a single +3V to +5.5V supply, ensure a 250kbps minimum data rate,
require only four small external 0.1µF capacitors, feature low power consumption, and meet all ElA RS-232C and
V.28 specifications.
4.1
Charge-Pump
The ICL32xxE family uses regulated on-chip dual charge-pumps as voltage doublers, and voltage inverters to
generate ±5.5V transmitter supplies from a VCC supply as low as 3.0V. The charge-pumps allow the devices to
maintain RS-232 compliant output levels over the ±10% tolerance range of 3.3V powered systems. The efficient
on-chip power supplies require only four small external 0.1µF capacitors for the voltage doubler and inverter
functions at VCC = 3.3V. See “Capacitor Selection” on page 21 and Table 6 on page 21 for capacitor
recommendations for other operating conditions. The charge-pumps operate discontinuously (they turn off as
soon as the V+ and V- supplies are pumped up to the nominal values) and provide significant power savings.
4.1.1 Charge-Pump Abs Max Ratings
These 3V to 5V RS-232 transceivers have been fully characterized for 3.0V to 3.6V operation, and at critical
points for 4.5V to 5.5V operation. Furthermore, load conditions were favorable using static logic states only.
The specified maximum values for V+ and V- are +7V and -7V, respectively. These limits apply for VCC values set
to 3.0V and 3.6V (see Table 2). For VCC values set to 4.5V and 5.5V, the maximum values for V+ and
V- can approach +9V and -7V, respectively (Table 3). The breakdown characteristics for V+ and V- were
measured with ±13V.

Transmitters
The transmitters are proprietary, low dropout, inverting drivers that translate TTL/CMOS inputs to EIA/TIA-232
output levels. The transmitters are coupled with the on-chip ±5.5V supplies and deliver true RS-232 levels across
a wide range of single supply system voltages.
Except for the ICL3232E, all transmitter outputs disable and assume a high impedance state when the device
enters the power-down mode (see Table 5 on page 18). The outputs can be driven to ±12V when disabled.
All devices operate at a 250kbps data rate for full load conditions (3kΩ and 1000pF), VCC ≥ 3.0V, with one
transmitter operating at full speed. Under more typical conditions of VCC ≥ 3.3V, RL = 3kΩ, and CL = 250pF, one
transmitter easily operates at 900kbps.
The transmitter inputs float if left unconnected and can increase ICC. Connect unused inputs to GND for the best
performance.
4.3
Receivers
All the ICL32xxE devices except for the ICL3232E contain standard inverting receivers that three-state from the
EN or FORCEOFF control lines. The two ICL324XE devices include noninverting (monitor) receivers (denoted by
the ROUTB label) that are always active, regardless of the state of any control lines. All the receivers convert
RS-232 signals to CMOS output levels and accept inputs up to ±25V while presenting the required 3kΩ to 7kΩ
input impedance (see Figure 7) even if the power is off (VCC = 0V). The receivers’ Schmitt trigger input stage uses
hysteresis to increase noise immunity and decrease errors due to slow input signal transitions.

Figure 7. Inverting Receiver Connections
The ICL3221E, ICL3222E, ICL3223E, and ICL3241E inverting receivers disable only when EN is driven high. The
ICL3243E receiver disables during forced (manual) power-down, but not during automatic power-down (see
Table 5 on page 18).
The ICL3241E and ICL3243E monitor receivers remain active even during manual power-down and forced
receiver disable, which makes them extremely useful for Ring Indicator monitoring. Standard receivers driving
powered down peripherals must be disabled to prevent current flow through the peripheral’s protection diodes
(see Figures 8 and 9). When disabled, the receivers cannot be used for wake up functions, but the corresponding
monitor receiver can be dedicated to this task, as shown in Figure 9.

4. Application Information
Low Power Operation
These 3V devices require a nominal supply current of 0.3mA, even at VCC = 5.5V, during normal operation (not in
power-down mode). This current is considerably less than the 5mA to 11mA current required by comparable 5V
RS-232 devices and allows you to reduce system power simply by switching to this family.
4.5
Power-Down Functionality (Except ICL3232E)
The already low current requirement drops significantly when the device enters power-down mode. In
power-down, the supply current drops to 1µA because the on-chip charge pump turns off (V+ collapses to VCC
and V- collapses to GND), and the transmitter outputs three-state. Inverting receiver outputs may disable in
power-down; see Table 5 for details. This micro-power mode makes these devices ideal for battery powered and
portable applications.
4.5.1 Software Controlled (Manual) Power-Down
Most devices in the ICL32xxE family provide pins that allow you to force the IC into the low power standby state.
On the ICL3222E and ICL3241E, the power-down control is a simple shutdown (SHDN) pin. Driving this pin high
enables normal operation, and driving it low forces the IC into its power-down state. Connect SHDN to VCC if the
power-down function is not needed. Note that all the receiver outputs remain enabled during shutdown (see
Table 5). For the lowest power consumption during power-down, the receivers should also be disabled by driving
the EN input high (see “Receiver ENABLE Control (ICL3221E, ICL3222E, ICL3223E, and ICL3241E Only)” on
page 21 and Figures 8 and 9).
The ICL3221E, ICL3223E, and ICL3243E use a two pin approach in which the FORCEON and FORCEOFF
inputs determine the IC’s mode. For always enabled operation, FORCEON and FORCEOFF are both strapped
high. Under logic or software control, only the FORCEOFF input needs to be driven to switch between active and
power-down modes. The FORCEON state is not critical because FORCEOFF overrides FORCEON. However, if
strictly manual control over power-down is needed, you must strap FORCEON high to disable the automatic
power-down circuitry. The ICL3243E inverting (standard) receiver outputs also disable when the device is in
manual power-down, which eliminates the possible current path through a shutdown peripheral’s input protection
diode (see Figures 8 and 9).

4.5.2 INVALID Output
The INVALID output always indicates whether a valid RS-232 signal is present at any of the receiver inputs (see
Table 5) and provides an easy way to determine when the interface block should power down. If an interface
cable is disconnected and all the receiver inputs are floating (but pulled to GND by the internal receiver pull down
resistors), the INVALID logic detects the invalid levels and drives the output low. The power management logic
then uses this indicator to power down the interface block. Reconnecting the cable restores valid levels at the
receiver inputs, INVALID switches high, and the power management logic wakes up the interface block. INVALID
can also indicate the DTR or RING INDICATOR signal as long as the other receiver inputs are floating or driven to
GND (as in the case of a powered down driver). Connecting FORCEOFF and FORCEON together disables the
automatic power-down feature and enables them to function as a manual SHUTDOWN input (see Figure 10).

With any of the control schemes, the time required to exit power-down and resume transmission is 100µs. A
mouse or other application may need more time to wake up from shutdown. If automatic power-down is used, the
RS-232 device reenters power-down if valid receiver levels are not reestablished within 30µs of the ICL32xxE

4.5.3 Automatic Power-Down (ICL3221E, ICL3223E, and ICL3243E Only)
Even greater power savings are available by using the ICL3221E, ICL3223E, or ICL3243E’s automatic
power-down function. When no valid RS-232 voltages are sensed on any receiver input for 30µs (see Figure 12),
the charge-pump and transmitters power down and reduce the supply current to 1µA. Invalid receiver levels occur
whenever the driving peripheral’s outputs are shut off (powered down) or when the RS-232 interface cable is
disconnected. The ICL32xxE powers back up whenever it detects a valid RS-232 voltage level on any receiver
input. The automatic power-down feature provides additional system power savings without changes to the
existing operating system.

Figure 12. Definition of Valid RS-232 Receiver Levels
Automatic power-down operates when the FORCEON input is low and the FORCEOFF input is high. Tying
FORCEON high disables automatic power-down, but manual power-down is always available with the overriding
FORCEOFF input. Table 5 on page 18 summarizes the automatic power-down functionality.
Devices with the automatic power-down feature include an INVALID output signal that switches low to indicate
that invalid levels have persisted on all of the receiver inputs for more than 30µs (see Figure 13). INVALID
switches high 1µs after detecting a valid RS-232 level on a receiver input. INVALID operates in all modes (forced
or automatic power-down, or forced on), so it is also useful for systems employing manual power-down circuitry.
When automatic power-down is used, INVALID = 0 indicates that the ICL32xxE is in power-down mode.
The time to recover from automatic power-down mode is typically 100µs.

Receiver ENABLE Control (ICL3221E, ICL3222E, ICL3223E, and ICL3241E Only)
The ICL3221E, ICL3222E, ICL3223E, and ICL3241E also feature an EN input to control the receiver outputs.
Driving EN high disables all the inverting (standard) receiver outputs and places them in a high impedance state.
The high impedance state is useful for eliminating supply current, due to a receiver output forward biasing the
protection diode when driving the input of a powered down (VCC = GND) peripheral (see Figure 8 on page 17).
The enable input has no effect on transmitter or monitor (ROUTB) outputs.
4.7
Capacitor Selection
The charge-pumps require 0.1µF capacitors for 3.3V operation. For other supply voltages, see Table 6 for
capacitor values. Do not use values smaller than those listed in Table 6. Increasing the capacitor values (by a
factor of 2) reduces ripple on the transmitter outputs and slightly reduces power consumption. C2, C3, and C4 can
be increased without increasing C1’s value; however, do not increase C1 without also increasing C2, C3, and C4 to
maintain the proper ratios (C1 to the other capacitors).
When using minimum required capacitor values, make sure that capacitor values do not degrade excessively with
temperature. If in doubt, use capacitors with a larger nominal value. The capacitor’s Equivalent Series Resistance
(ESR) usually rises at low temperatures and it influences the amount of ripple on V+ and V-.

Power Supply Decoupling
In most circumstances, a 0.1µF bypass capacitor is adequate. In applications that are particularly sensitive to
power supply noise, decouple VCC to ground with a capacitor of the same value as the charge-pump capacitor C1.
Connect the bypass capacitor as close as possible to the IC.
4.9
Operation Down to 2.7V
The ICL32xxE transmitter outputs meet RS-562 levels (±3.7V) at full data rate, with VCC as low as 2.7V. RS-562
levels typically ensure interoperability with RS-232 devices.

Transmitter Outputs when Exiting Power-Down
Figure 14 shows the response of two transmitter outputs when exiting power-down mode. As they activate, the
two transmitter outputs properly go to opposite RS-232 levels, with no glitching, ringing, or undesirable transients.
Each transmitter is loaded with 3kΩ in parallel with 2500pF. Note that the transmitters enable only when the
magnitude of the supplies exceeds approximately 3V.

Mouse Driveability
The ICL3241E and ICL3243E are specifically designed to power a serial mouse while operating from low voltage
supplies. Figure 15 shows the transmitter output voltages under increasing load current. The on-chip switching
regulator ensures the transmitters supply at least ±5V during worst case conditions (15mA for paralleled V+
transmitters, 7.3mA for a single V- transmitter). The Automatic Power-Down feature does not work with a mouse,
so FORCEOFF and FORCEON should be connected to VCC.

High Data Rates
The ICL32xxE devices maintain the RS-232 ±5V minimum transmitter output voltages even at high data rates.
Figure 16 shows a transmitter loopback test circuit and Figure 17 shows the loopback test result at 120kbps. For
this test, all transmitters were simultaneously driving RS-232 loads in parallel with 1000pF at 120kbps. Figure 18
shows the loopback results for a single transmitter driving 1000pF and an RS-232 load at 250kbps. The static
transmitters were also loaded with an RS-232 receiver.

Interconnection with 3V and 5V Logic
The ICL32Exx devices directly interface with 5V CMOS and TTL logic families. The AC, HC, and CD4000 outputs
can drive ICL32Exx inputs with the ICL32Exx at 3.3V and the logic supply at 5V, but ICL32Exx outputs do not
reach the minimum VIH for these logic families. See Table 7.

Pin-Compatible Replacements for 5V Devices
The ICL3221E, ICL3222E, and ICL3232E are pin-compatible with existing 5V RS-232 transceivers. See
“Features” on page 1 for more information.
The pin compatibility coupled with the low ICC and wide operating supply range make the ICL32xxE potential
lower power, higher performance drop-in replacements for existing 5V applications. The ICL32xxE works in most
5V applications as long as the ±5V RS-232 output swings are acceptable and transmitter input pull-up resistors
are not required.
When replacing a device in an existing 5V application, you can terminate C3 to VCC as shown in the “Typical
Operating Circuits” on page 4. If possible, terminate C3 to GND for slightly better performance.

5. ±15kV ESD Protection
±15kV ESD Protection
All pins on the ICL32Exx devices include ESD protection structures, but the ICL32xxE family incorporates
advanced structures that allow the RS-232 pins (transmitter outputs and receiver inputs) to survive ESD events
up to ±15kV. The RS-232 pins are particularly vulnerable to ESD damage because they typically connect to an
exposed port on the exterior of the finished product. Touching the port pins or connecting a cable, can cause an
ESD event that might destroy unprotected ICs. The ESD structures protect the device whether or not it is powered
up, protect without allowing any latch-up mechanism to activate, and do not interfere with RS-232 signals as large
as ±25V.
5.1
Human Body Model (HBM) Testing
This test method emulates the ESD event delivered to an IC during human handling. The tester delivers the
charge through a 1.5kΩ current limiting resistor and makes the test less severe than the IEC61000 test, which
uses a 330Ω limiting resistor. The HBM method determines an IC’s ability to withstand the ESD transients
typically present during handling and manufacturing. Due to the random nature of these events, each pin is tested
with respect to all other pins. The RS-232 pins on “E” family devices can withstand HBM ESD events to ±15kV.
5.2
IEC61000-4-2 Testing
The IEC61000 test method applies to finished equipment rather than to an individual IC. Therefore, the pins most
likely to suffer an ESD event are those that are exposed to the outside world (the RS-232 pins in this case), and
the IC is tested in its typical application configuration (power applied) rather than testing each pin-to-pin
combination. The lower current limiting resistor coupled with the larger charge storage capacitor yields a test that
is much more severe than the HBM test. The extra ESD protection built into this device’s RS-232 pins allows the
design of equipment meeting level 4 criteria without the need for additional board level protection on the
RS-232 port.
5.3
Air-Gap Discharge Test Method
For the air-gap discharge test method, a charged probe tip moves toward the IC pin until the voltage arcs to it.
The current waveform delivered to the IC pin depends on factors such as approach speed, humidity, and
temperature, so it is difficult to obtain repeatable results. The “E” device RS-232 pins withstand ±15kV air-gap
discharges.
5.4
Contact Discharge Test Method
During the contact discharge test, the probe contacts the tested pin before the probe tip is energized and
eliminates the variables associated with the air-gap discharge. The test is more repeatable and predictable, but
equipment limits prevent testing devices at voltages higher than ±8kV. All “E” family devices survive ±8kV contact
discharges on the RS-232 pins.
