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, V
CC
and V
L
, set the logic lev-
els 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 unidirectional
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 (see 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.)
