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

logic levels on either side of the device. A low-voltage

device, and vice-versa. The MAX3374E/MAX3375E/

MAX3376E/MAX3379E and MAX3390E–MAX3393E unidi-

rectional level translators level shift data in one direction

MAX3372E/MAX3373E and MAX3377E/MAX3378E bidi-

rectional level translators utilize a transmission-gate-

based design (Figure 2) to allow data translation in either

MAX3372E–MAX3379E and MAX3390E–MAX3393E

+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-

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.
