1.8V to 3.3V, Micro-Power, ±15kV ESD, +125 °C, Slew Rate Limited
RS-485/RS-422 Transceivers
The ISL32600E, ISL32601E, ISL32602E, and ISL32603E are
±15kV IEC61000 ESD protected, micro-power, wide supply
range transceivers for differential communication. The
ISL32600E and ISL32601E operate with VCC ≥ 2.7V and have
maximum supply currents as low as 100µA with both the
transmitter (Tx) and receiver (Rx) enabled. The ISL32602E and
ISL32603E operate with supply voltages as low as 1.8V. These
transceivers have very low bus currents, so they present less
than a 1/8 unit load to the bus. This allows more than 256
transmitters on the network without violating the RS-485
specification’s 32 unit load maximum.
Features
The Rx inputs feature symmetrical switching thresholds and up
to 65mV of hysteresis to improve noise immunity and to
reduce duty cycle distortion in the presence of slow moving
input signals (see Figure 39 on page 18). The Rx input
common-mode range is the full -7V to +12V RS-485 range for
supply voltages ≥ 3V.
• Symmetrical switching thresholds for less duty cycle
distortion (see Figure 39 on page 18)
Hot plug circuitry ensures that the Tx and Rx outputs remain in
a high impedance state while the power supply stabilizes.
• 1/8 unit load allows up to 256 devices on the bus
This transceiver family uses slew rate limited drivers, which
reduce EMI, and minimize reflections from improperly terminated
transmission lines or from unterminated stubs in multidrop and
multipoint applications.
• Half and full duplex pinouts; three state Rx and Tx outputs
The ISL32600E and ISL32602E are configured for full duplex
(separate Rx input and Tx output pins) applications. The
ISL32601E and ISL32603E are half duplex versions that
multiplex the Rx inputs and Tx outputs to allow transceivers
with output disable functions in 8 Ld packages. Table 1 on
page 3 provides a summary of each device’s features.

NOTES:
6. All currents into device pins are positive; all currents out of device pins are negative. All voltages are referenced to device ground unless otherwise
specified.
7. Supply current specification is valid for loaded drivers when DE = 0V.
8. Applies to peak current. See “Typical Performance Curves” starting on page 13 for more information.
9. When testing this parameter, keep RE = 0 to prevent the device from entering SHDN.
10. When testing this parameter, the RE signal high time must be short enough (typically 600ns (1200ns if VCC = 1.8V) to ensure that the device enters SHDN.
13. Set the RE signal high time >600ns (1200ns if VCC = 1.8V) to ensure that the device enters SHDN.
14. If the Tx or Rx enable function is not needed, connect the enable pin to the appropriate supply (see “Pin Descriptions” on page 4).
15. Compliance to datasheet limits is assured by one or more methods: production test, characterization, and/or design.

Application Information
SUBSTRATE POTENTIAL (POWERED UP):
RS-485 and RS-422 are differential (balanced) data
transmission standards for use in long haul or noisy
environments. RS-422 is a subset of RS-485, so RS-485
transceivers are also RS-422 compliant. RS-422 is a
point-to-multipoint (multidrop) standard, which allows only one
driver and up to 10 receivers on each bus, assuming one unit
load devices. RS-485 is a true multipoint standard, which allows
up to 32 one-unit load devices (any combination of drivers and
receivers) on each bus. To allow for multipoint operation, the
RS-485 specification requires that drivers must handle bus
contention without sustaining any damage.

ISL32600E, ISL32601E, ISL32602E, ISL32603E
Another important advantage of RS-485 is the extended
Common-Mode Range (CMR), which specifies that the driver
outputs and receiver inputs withstand signals that range from
-7V to +12V. RS-422 and RS-485 are intended for runs as long as
4000ft, so the wide CMR is necessary to handle ground potential
differences and voltages induced in the cable by external fields.
Receiver Features
RECEIVER OUTPUT (V) RECEIVER INPUT (V)
The ISL3260xE devices use a differential input receiver for
maximum noise immunity and common-mode rejection. Input
sensitivity is greater than ±200mV, as required by the RS-422
and RS-485 specifications. The symmetrical ±200mV switching
thresholds eliminate the duty cycle distortion that occurs on
receivers with Full Fail Safe (FFS) functionality and with slowly
transitioning input signals (see Figure 39). FFS receiver switching
points have a negative offset, so the RO high time is naturally
longer than the low time. The ISL3260xE’s larger receiver input
sensitivity range enables an increase of the receiver input
hysteresis. The 40mV to 65mV receiver hysteresis increases the
noise immunity, which is an advantage for noisy networks or
networks with slow bus transitions.

pull-down on inverting input) to preserve the bus idle state when
the bus is not actively driven.
Receivers operate at data rates from 128kbps to 460kbps
depending on the supply voltage, and all receiver outputs are
tri-statable using the active low RE input. There are no parasitic
diodes nor ESD diodes to VCC on the RE input, so RE is tolerant of
input voltages up to 5.5V, even with the ISL3260xE powered
down (VCC = 0V).
Driver Features
The ISL3260xE drivers are differential output devices that deliver
at least 1.4V with VCC ≥ 3V across a 54Ω load (RS-485) and at
least 1.95V with VCC ≥ 3.15V across a 100Ω load (RS-422). The
1.8V transmitters deliver a 1.1V unloaded, differential level.
Drivers operate at data rates from 128kbps to 460kbps
depending on the supply voltage, and they feature low
propagation delay skews to maximize bit width. Driver outputs
are slew rate limited to minimize EMI and to reduce reflections in
unterminated or improperly terminated networks.
All drivers are tri-statable using the active high DE input. There
are no parasitic diodes nor ESD diodes to VCC on the DI and DE
inputs, so these inputs are tolerant of input voltages up to 5.5V,
even with the ISL3260xE powered down (VCC = 0V).

SIGNALS
The receiver input resistance of 96kΩ surpasses the RS-422
specification of 4kΩ and is eight times the RS-485 Unit Load (UL)
requirement of 12kΩ minimum. Therefore, these products are
known as “one-eighth UL” transceivers and there can be up to
256 of these devices on a network while still complying with the
RS-485 loading specification.
Receiver inputs function with common-mode voltages as great as
+9V/-7V outside the power supplies (that is, +12V and -7V) at
VCC = 3V, making them ideal for long networks where induced
voltages and ground potential differences are realistic concerns.
The positive CMR is limited to +2V when the ISL32602E or
ISL32603E is operated with VCC = 1.8V.
All the receivers include a “fail-safe if open” function that assures
a high level receiver output if the receiver inputs are unconnected
(floating). Because the Rx is not FFS, terminated networks may
require bus biasing resistors (pull-up on noninverting input,
FN7967 Rev.3.0
May 28, 2021
The ISL32602E and ISL32603E are specifically designed to
operate with supply voltages as low as 1.8V. Avoid termination
resistors at this operating condition, and the unterminated driver
is assured to deliver a healthy 1.1V differential output voltage.
This low supply voltage limits the +CMR to +2V, but the CMR
increases as VCC increases.
For proper 1.8V operation, the ISL32602E and ISL32603E must
run at a higher operating current. Therefore, their ICC with
VCC = 3.3V is considerably higher than the ICC of the ISL32600E
and ISL32601E, which are optimized for low ICC at 3.3V (see
Figures 1 and 2).
Hot Plug Function
When a piece of equipment powers up, a period of time when the
processor or ASIC driving the RS-485 control lines (DE, RE) is
unable to ensure that the RS-485 Tx and Rx outputs are kept
disabled. If the equipment is connected to the bus, a driver
activating prematurely during power-up may crash the bus. To
avoid this scenario, the ISL3260xE devices incorporate a hot plug
function. During power-up, circuitry monitoring VCC ensures that the
Tx and Rx outputs remain disabled for a period of time, regardless of
the state of DE and RE. This gives the processor/ASIC a chance to
stabilize and drive the RS-485 control lines to the proper states.
ESD Protection
All pins on the ISL3260xE devices include Class 3 (>8kV) Human
Body Model (HBM) ESD protection structures, but the RS-485 pins
(driver outputs and receiver inputs) incorporate advanced
structures allowing them to survive ESD events in excess of ±15kV
HBM and ±15kV IEC61000. The RS-485 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 can
destroy unprotected ICs. The new ESD structures protect the device
Page 18 of 24
ISL32600E, ISL32601E, ISL32602E, ISL32603E
whether or not it is powered up without degrading the transceiver’s
CMR. The built-in ESD protection eliminates the need for board
level protection structures such as transient suppression diodes
and the associated undesirable capacitive load they present.
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-485 pins in this case), 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-485 pins allows the design of equipment meeting
Level 4 criteria without the need for additional board level
protection on the RS-485 port.
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 approach speed,
humidity, temperature, etc. so it is difficult to obtain repeatable
results. The ISL3260xE RS-485 pins withstand ±15kV air-gap
discharges.
CONTACT DISCHARGE TEST METHOD
multi-receiver applications, keep stubs connecting receivers to
the main cable as short as possible. Multipoint (multi-driver)
systems require that the main cable be terminated in its
characteristic impedance at both ends. Keep stubs connecting a
transceiver to the main cable as short as possible.
Terminated networks using the ISL3260xE may require bus
biasing resistors (pull-up on noninverting input, pull-down on
inverting input) to preserve the bus idle state when the bus is not
actively driven. Without bus biasing, the termination resistor
collapses the undriven, differential bus voltage to 0V, which is an
undefined level to the ISL3260xE Rx. Bus biasing forces a few
hundred mV positive differential voltage on the undriven bus,
which all RS-485 and RS-422 Rx interpret as a valid logic high.
Built-In Driver Overload Protection
As stated previously, the RS-485 specification requires that
drivers survive worst case bus contentions undamaged. These
devices meet this requirement using driver output short-circuit
current limits and on-chip thermal shutdown circuitry.
The driver output stages incorporate short-circuit current limiting
circuitry that ensures that the output current never exceeds the
RS-485 specification, even at the common-mode voltage range
extremes. Additionally, these devices use a foldback circuit which
reduces the short-circuit current, and thus the power dissipation,
whenever the contending voltage exceeds either supply.
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 result is a
more repeatable and predictable test, but equipment limits
prevent testing devices at voltages higher than ±8kV. The
ISL3260xE devices survive ±8kV contact discharges on the
RS-485 pins.
In the event of a major short-circuit condition, the ISL3260xE’s
thermal shutdown feature disables the drivers whenever the die
temperature becomes excessive. Thermal shutdown eliminates
the power dissipation, allowing the die to cool. The drivers
automatically re-enable after the die temperature drops by about
20°C. If the condition persists, the thermal shutdown/re-enable
cycle repeats until the fault is cleared. Receivers remain
operational during thermal shutdown.
Data Rate, Cables, and Terminations
Low Power Shutdown Mode
RS-485/422 are intended for network lengths up to 4000ft
(1220m), but the maximum system data rate decreases as the
transmission length increases. The ISL32600E and ISL32601E
operate at data rates up to 128kbps at the maximum (4000ft)
distance, or at data rates of 256kbps for cable lengths less than
3000ft (915m). The ISL32602E and ISL32603E, with VCC = 1.8V,
are limited to 1000ft (305m) at 256kbps, or 2000ft (610m) at
128kbps. With VCC = 3.3V, the ISL32602E and ISL32603E
deliver 460kbps over 2000ft, 256kbps over 3000ft, or 128kbps
over 4000ft cables.
These micro-power transceivers all use a fraction of the power
required by their counterparts, but they also include a shutdown
feature that reduces the already low quiescent ICC to a 10nA
trickle. These devices enter shutdown whenever the receiver and
driver are simultaneously disabled (RE = VCC and DE = GND) for a
period of at least 600ns (1200ns at VCC = 1.8V). Disabling both
the driver and the receiver for fewer than 50ns assures that the
transceiver does not enter shutdown.
Twisted pair is the cable of choice for RS-485 and RS-422
networks. Twisted pair cables tend to pick up noise and other
electromagnetically induced voltages as common-mode signals
that are effectively rejected by the differential receivers in these
ICs.
Note that most receiver and driver enable times increase when the
transceiver enables from shutdown. See Notes 9 through 13 on
page 10 for more information.
Short networks using these transceivers need not be terminated,
but terminations are recommended for 2.7V to 3.6V powered
networks unless power dissipation is an overriding concern.
Terminations are not recommended for 1.8V applications due to
the low drive available from those transmitters.
