The MAX3372E–MAX3379E and MAX3390E–MAX3393E

ESD-protected level translators provide the level shifting

necessary to allow data transfer in a multivoltage system.

rectional level translators utilize a transmission-gate-

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

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 Timing Characteristics.)
