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

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

signals externally. The MAX3372E/MAX3377E operate  
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.)

UCSP is a trademark of Maxim Integrated Products, Inc.  
The MAX3372E–MAX3376E are dual level shifters avail-  
able 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.
