±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, V
CC
and V
L
, set the
logic levels on either side of the device. A low-voltage
logic signal present on the V
L
side of the device appears
as a high-voltage logic signal on the V
CC
side of the
device, and vice-versa. The MAX3374E/MAX3375E/
MAX3376E/MAX3379E and MAX3390E–MAX3393E unidi-
rectional level translators level shift data in one direction
(V
L
→
V
CC
or V
CC
→
V
L
) on any single data line. The
MAX3372E/MAX3373E and MAX3377E/MAX3378E bidi-
rectional level translators utilize a transmission-gate-
based 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 V
L
from +1.2V to +5.5V and V
CC
from +1.65V to
+5.5V, making them ideal for data transfer between low-
voltage 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 short-
circuit protection, and ±15kV ESD protection on the V
CC
side for greater protection in applications that route sig-
nals 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 14-
pin TSSOP packages.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
