General Description
The MAX3372E–MAX3379E and MAX3390E–MAX3393E
±15kV ESD-protected level translators provide the level
shifting necessary to allow data transfer in a multivolt-
age 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 uni-
directional level translators level shift data in one direc-
tion (V
L
→ V
CC
or V
CC
→ V
L
) on any single data line.
The MAX3372E/MAX3373E and MAX3377E/MAX3378E
bidirectional 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
shortcircuit protection, and ±15kV ESD protection on the
V
CC
side for greater protection in applications that route
signals externally. The MAX3372E/MAX3377E operate
at a guaranteed data rate of 230kbps. Slew-rate limit-
ing 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 avail-
able 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.
