The MAX1489E quad, low-power line receiver is
designed for EIA/TIA-232, EIA/TIA-562, and CCITT V.28
communications in harsh environments. Each receiver
input is protected against ±15kV electrostatic dis-
charge (ESD) shocks. These inputs have a ±25V range
and feature hysteresis and time-domain filtering. The
outputs are TTL and CMOS compatible. The MAX1489E
has a 120kbps guaranteed data rate. Supply current is
typically 350µA.
The MAX1489E is pin compatible with the MC1489,
MC14C89, SN75189, SN75C189, DS1489, and
DS14C89. It is available in 14-pin plastic DIP and SO
packages.
