General Description

The MAX1488E quad, low-power line driver is designed for EIA/TIA-232, EIA/TIA-562, and CCITT V.28 communications in harsh environments. Each transmitter output is protected against ±15kV electrostatic discharge (ESD) shocks. The inputs are TTL and CMOS compatible 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.
