MAX1489E 19-0426 Rev 1 2/03 15kV ESD-Protected, Quad, Low-Power RS-232 Line Receiver General Description Features The MAX1489E quad, low-power line receiver is Enhanced ESD Protection: designed for EIA/TIA-232, EIA/TIA-562, and CCITT V.28 15kVHuman Body Model communications in harsh environments. Each receiver 8kVIEC1000-4-2, Contact Discharge input is protected against 15kV electrostatic dis- 15kVIEC1000-4-2, Air-Gap Discharge charge (ESD) shocks. These inputs have a 25V range and feature hysteresis and time-domain filtering. The Latchup Free During an ESD Event outputs are TTL and CMOS compatible. The MAX1489E Low 350A Supply Current has a 120kbps guaranteed data rate. Supply current is Input Hysteresis and Time-Domain Filtering typically 350A. Eliminate the Need for External Filtering The MAX1489E is pin compatible with the MC1489, MC14C89, SN75189, SN75C189, DS1489, and Stable Input Thresholds DS14C89. It is available in 14-pin plastic DIP and SO Pin Compatible with MC1489, MC14C89, SN75189, packages.
