MAX3372E–MAX3379E/
MAX3390E–MAX3393E
±15kV ESD-Protected, 1µA, 16Mbps, Dual/Quad
Low-Voltage Level Translators in UCSP
General Description
The MAX3372E–MAX3379E and MAX3390E–MAX3393E
±15kV ESD-protected level translators provide the level
shifting necessary to allow data transfer in a multivoltage
system. Externally applied voltages, VCC and VL, set the
logic levels on either side of the device. A low-voltage
logic signal present on the VL side of the device appears
as a high-voltage logic signal on the VCC side of the
device, and vice-versa. The MAX3374E/MAX3375E/
MAX3376E/MAX3379E and MAX3390E–MAX3393E unidirectional level translators level shift data in one direction
(VL → VCC or VCC → VL) on any single data line. The
MAX3372E/MAX3373E and MAX3377E/MAX3378E bidirectional level translators utilize a transmission-gatebased design (Figure 2) to allow data translation in either
direction (V L ↔ V CC ) on any single data line. The
MAX3372E–MAX3379E and MAX3390E–MAX3393E
accept VL from +1.2V to +5.5V and VCC from +1.65V to
+5.5V, making them ideal for data transfer between lowvoltage ASICs/PLDs and higher voltage systems.
All devices in the MAX3372E–MAX3379E, MAX3390E–
MAX3393E family feature a three-state output mode that
reduces supply current to less than 1µA, thermal shortcircuit protection, and ±15kV ESD protection on the VCC
side for greater protection in applications that route signals externally. The MAX3372E/MAX3377E operate at a
guaranteed data rate of 230kbps. Slew-rate limiting
reduces EMI emissions in all 230kbps devices. The
MAX3373E–MAX3376E/MAX3378E/MAX3379E and
MAX3390E–MAX3393E operate at a guaranteed data rate
of 8Mbps over the entire specified operating voltage
range. Within specific voltage domains, higher data rates
are possible. (See the Timing Characteristics table.)
The MAX3372E–MAX3376E are dual level shifters
available in 3 x 3 UCSP™, 8-pin TDFN, and 8-pin
SOT23-8 packages. The MAX3377E/MAX3378E/
MAX3379E and MAX3390E–MAX3393E are quad level
shifters available in 3 x 4 UCSP, 14-pin TDFN, and 14pin TSSOP packages.

Note 1: All units are 100% production tested at TA = +25°C. Limits over the operating temperature range are guaranteed by design
and not production tested.
Note 2: For normal operation, ensure VL < (VCC + 0.3V). During power-up, VL > (VCC + 0.3V) will not damage the device.
Note 3: To ensure maximum ESD protection, place a 1µF capacitor between VCC and GND. See Applications Circuits.

Low-Voltage Level Translators in UCSP
Detailed Description
The MAX3372E–MAX3379E and MAX3390E–MAX3393E
ESD-protected level translators provide the level shifting
necessary to allow data transfer in a multivoltage system.
Externally applied voltages, VCC and VL, set the logic levels on either side of the device. A low-voltage logic signal
present on the VL side of the device appears as a highvoltage logic signal on the VCC side of the device, and
vice-versa. The MAX3374E/MAX3375E/MAX3376E/
MAX3379E and MAX3390E–MAX3393E unidirectional
level translators level shift data in one direction (VL →
V CC or V CC → V L ) on any single data line. The
MAX3372E/MAX3373E and MAX3377E/MAX3378E bidirectional level translators utilize a transmission-gatebased design (see Figure 2) to allow data translation in
either direction (VL ↔ VCC) on any single data line. The
MAX3372E–MAX3379E and MAX3390E–MAX3393E
VL
accept VL from +1.2V to +5.5V and VCC from +1.65V to
+5.5V, making them ideal for data transfer between lowvoltage ASICs/PLDs and higher voltage systems.
All devices in the MAX3372E–MAX3379E, MAX3390E–
MAX3393E family feature a three-state output mode that
reduces supply current to less than 1µA, thermal shortcircuit protection, and ±15kV ESD protection on the VCC
side for greater protection in applications that route signals externally. The MAX3372E/MAX3377E operate at a
guaranteed data rate of 230kbps. Slew-rate limiting
reduces EMI emissions in all 230kbps devices. The
MAX3373E–MAX3376E/MAX3378E/MAX3379E and
MAX3390E–MAX3393E operate at a guaranteed data rate
of 8Mbps over the entire specified operating voltage
range. Within specific voltage domains, higher data rates
are possible. (See the Timing Characteristics table.)

Level Translation
For proper operation ensure that +1.65V ≤ V CC ≤
+5.5V, +1.2V ≤ VL ≤ +5.5V, and VL ≤ (VCC + 0.3V).
During power-up sequencing, VL ≥ (VCC + 0.3V) will
not damage the device. During power-supply sequencing, when VCC is floating and VL is powering up, a current may be sourced, yet the device will not latch up.
The speed-up circuitry limits the maximum data rate for
devices in the MAX3372E–MAX3379E, MAX3390E–
MAX3393E family to 16Mbps. The maximum data rate
also depends heavily on the load capacitance (see the
Typical Operating Characteristics), output impedance
of the driver, and the operational voltage range (see the
Timing Characteristics table).
Speed-Up Circuitry
The MAX3373E–MAX3376E/MAX3378E/MAX3379E and
MAX3390E–MAX3393E feature a one-shot generator that
decreases the rise time of the output. When triggered,
MOSFETs PU1 and PU2 turn on for a short time to pull up
VL
I/O VL_ and I/O VCC_ to their respective supplies (see
Figure 2b). This greatly reduces the rise time and propagation delay for the low-to-high transition. The scope
photo of Rail-to-Rail Driving for 8Mbps Operation in the
Typical Operating Characteristics shows the speed-up
circuitry in operation.
Rise-Time Accelerators
The MAX3373E–MAX3376E/MAX3378E/MAX3379E and
the MAX3390E–MAX3393E have internal rise-time
accelerators allowing operation up to 16Mbps. The
rise-time accelerators are present on both sides of the
device and act to speed up the rise time of the input
and output of the device, regardless of the direction of
the data. The triggering mechanism for these accelerators is both level and edge sensitive. To prevent false
triggering of the rise-time accelerators, signal fall times
of less than 20ns/V are recommended for both the
inputs and outputs of the device. Under less noisy conditions, longer signal fall times may be acceptable.

Pull THREE-STATE low to place the MAX3372E–
MAX3379E and MAX3390E–MAX3393E in three-state output mode. Connect THREE-STATE to VL (logic-high) for
normal operation. Activating the three-state output mode
disconnects the internal 10kΩ pullup resistors on the I/O
VCC and I/O VL lines. This forces the I/O lines to a highimpedance state, and decreases the supply current to
less than 1µA. The high-impedance I/O lines in threestate output mode allow for use in a multidrop network.
When in three-state output mode, do not allow the voltage
Thermal Short-Circuit Protection
Thermal overload detection protects the MAX3372E–
MAX3379E and MAX3390E–MAX3393E from short-circuit
fault conditions. In the event of a short-circuit fault, when
the junction temperature (TJ) reaches +152°C, a thermal
sensor signals the three-state output mode logic to force
the device into three-state output mode. When TJ has
cooled to +142°C, normal operation resumes.

±15kV ESD Protection
As with all Maxim devices, ESD-protection structures are
incorporated on all pins to protect against electrostatic
discharges encountered during handling and assembly.
The I/O VCC lines have extra protection against static
electricity. Maxim’s engineers have developed state-ofthe-art structures to protect these pins against ESD of
±15kV without damage. The ESD structures withstand
high ESD in all states: normal operation, three-state
output mode, and powered down. After an ESD event,
Maxim’s E versions keep working without latchup,
whereas competing products can latch and must be
powered down to remove latchup.
ESD protection can be tested in various ways. The I/O
VCC lines of this product family are characterized for
protection to the following limits:
1) ±15kV using the Human Body Model
2) ±8kV using the Contact Discharge method specified
in IEC 1000-4-2
3) ±10kV using IEC 1000-4-2’s Air-Gap Discharge
method
ESD Test Conditions
ESD performance depends on a variety of conditions.
Contact Maxim for a reliability report that documents
test setup, test methodology, and test results.
Human Body Model
Figure 3a shows the Human Body Model and Figure 3b
shows the current waveform it generates when discharged into a low impedance. This model consists of
a 100pF capacitor charged to the ESD voltage of interest, which is then discharged into the test device
through a 1.5kΩ resistor.
RC 1MΩ
CHARGE-CURRENTLIMIT RESISTOR
IEC 1000-4-2
The IEC 1000-4-2 standard covers ESD testing and
performance of finished equipment; it does not specifically refer to integrated circuits. The MAX3372E–
MAX3379E and MAX3390E–MAX3393E help to design
equipment that meets Level 3 of IEC 1000-4-2, without
the need for additional ESD-protection components.
The major difference between tests done using the
Human Body Model and IEC 1000-4-2 is higher peak
current in IEC 1000-4-2, because series resistance is
lower in the IEC 1000-4-2 model. Hence, the ESD withstand voltage measured to IEC 1000-4-2 is generally
lower than that measured using the Human Body Model.
Figure 4a shows the IEC 1000-4-2 model, and Figure 4b
shows the current waveform for the ±8kV, IEC 1000-4-2,
Level 4, ESD contact-discharge test.
The air-gap test involves approaching the device with a
charged probe. The contact-discharge method connects the probe to the device before the probe
is energized.
Machine Model
The Machine Model for ESD tests all pins using a
200pF storage capacitor and zero discharge resistance. Its objective is to emulate the stress caused by
contact that occurs with handling and assembly during
manufacturing. Of course, all pins require this protection during manufacturing, not just inputs and outputs.
Therefore, after PCB assembly, the Machine Model is
less relevant to I/O ports.

Applications Information
ASIC and an I2C device. A typical application involves
interfacing a low-voltage microprocessor to a 3V or 5V
D/A converter, such as the MAX517.
Power-Supply Decoupling
To reduce ripple and the chance of transmitting incorrect data, bypass VL and VCC to ground with a 0.1µF
capacitor. See the Typical Operating Circuit. To ensure
full ±15kV ESD protection, bypass VCC to ground with a
1µF capacitor. Place all capacitors as close to the
power-supply inputs as possible.
Push-Pull vs. Open-Drain Driving
All devices in the MAX3372E–MAX3379E and
MAX3390E–MAX3393E family may be driven in a pushpull configuration. The MAX3373E–MAX3376E/
MAX3378E/MAX3379E and MAX3390E–MAX3393E
include internal 10kΩ resistors that pull up I/O VL_ and
I/O VCC_ to their respective power supplies, allowing
operation of the I/O lines with open-drain devices. See
the Timing Characteristics table for maximum data rates
when using open-drain drivers.
I2C Level Translation
The MAX3373E–MAX3376E, MAX3378E/MAX3379E
and MAX3390E–MAX3393E level-shift the data present
on the I/O lines between +1.2V and +5.5V, making
them ideal for level translation between a low-voltage
