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. 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.
The MAX1488E is a quad, low‑power RS‑232 line driver designed for harsh environments. It offers +15 kV ESD protection, internal slew‑rate limiting, and a guaranteed 120 kbps data rate while drawing less than 180 µA supply current.
The device is available in 14‑pin plastic DIP and SO packages, is pin‑compatible with several legacy parts, and includes detailed electrical characteristics, absolute maximum ratings, and package dimensions for designers.
