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.
