Quad Receiver RS-232 14-Pin PDIP N

The MAX1489E quad, low-power line receiver isdesigned for EIA/TIA-232, EIA/TIA-562, and CCITT V.28communications in harsh environments. Each receiverinput is protected against ±15kV electrostatic discharge(ESD) shocks. These inputs have a ±25V rangeand feature hysteresis and time-domain filtering. Theoutputs are TTL and CMOS compatible. The MAX1489Ehas a 120kbps guaranteed data rate. Supply current istypically 350µA. The MAX1489E is pin compatible with the MC1489,MC14C89, SN75189, SN75C189, DS1489, andDS14C89. It is available in 14-pin plastic DIP and SOpackages.
