MAX1489E
±15kV ESD-Protected, Quad, Low-Power RS-232 Line Receiver
|
Status
Active: In Production.
Description
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 discharge (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.
