_______________General Description

The MAX1488E quad, low-power line driver is designed

for EIA/TIA-232, EIA/TIA-562, and CCITT V.28 commu-

nications in harsh environments. Each transmitter out-

put is protected against ±15kV electrostatic discharge

(ESD) shocks. The inputs are TTL and CMOS compati-

ble with minimal loading. The outputs feature internally

controlled slew-rate limiting and current limiting. This

device has a guaranteed 120kbps data rate. Power-

supply current is less than 180µA over a ±4.5V to

±13.2V supply voltage range.

The MAX1488E is pin compatible with the MC1488,

MC14C88, SN75188, SN75C188, DS1488, and

DS14C88. It is available in 14-pin plastic DIP and SO

packages.
