MAX3372E–MAX3379E/
MAX3390E–MAX3393E
±15kV ESD-Protected, 1μA, 16Mbps, Dual/Quad
Low-Voltage Level Translators in UCSP
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

● Slew-Rate Limiting Lowers EMI
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

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.)
