General 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.

Features
♦ 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

Applications
   PC Motherboards
   Modems
   Interfacing Data Terminal Equipment (DTE) with
      Data Circuit-Terminating Equipment (DCE)
   Equipment Meeting IEC1000-4-2 (formerly
      IEC801-2) or ±15kV ESD Protection
