Maxim Integrated 

±15kV ESD-Protected, 1µA, 16Mbps, Dual/Quad

Low-Voltage Level Translators in UCSP

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, VCC and VL, set the logic lev-

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

present on the VL side of the device appears as a high-

voltage logic signal on the VCC side of the device, and

vice-versa. The MAX3374E/MAX3375E/MAX3376E/

MAX3379E and MAX3390E–MAX3393E unidirectional

level translators level shift data in one direction (VL →

VCC or VCC → VL) 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 (VL ↔ VCC) on any single data line. The

MAX3372E–MAX3379E and MAX3390E–MAX3393E

accept VL from +1.2V to +5.5V and VCC 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 VCC

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.)
