Quad Receiver RS-232 14-Pin SOIC 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.

• Enhanced ESD Protection: ±15kV—Human Body Model ±8kV—IEC1000-4-2, Contact Discharge ±15kV—IEC1000-4-2, Air-Gap Discharge
• Latchup Free During an ESD Event
• Low 350µA Supply Current
• Input Hysteresis and Time-Domain Filtering Eliminate the Need for External Filtering
• Stable Input Thresholds
• Pin Compatible with MC1489, MC14C89, SN75189, SN75C189, DS1489, and DS14C89
