MAX1489E

MAX1489E 19-0426; Rev 1; 2/03 ±15kV ESD-Protected, Quad, Low-Power RS-232 Line Receiver _______________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. 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. ________________________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 ____________________________Features o Enhanced ESD Protection: ±15kV—Human Body Model ±8kV—IEC1000-4-2, Contact Discharge ±15kV—IEC1000-4-2, Air-Gap Discharge o Latchup Free During an ESD Event o Low 350µA Supply Current o Input Hysteresis and Time-Domain Filtering Eliminate the Need for External Filtering o Stable Input Thresholds o Pin Compatible with MC1489, MC14C89, SN75189, SN75C189, DS1489, and DS14C89 ______________Ordering Information PART TEMP RANGE MAX1489ECPD 0°C to +70°C MAX1489ECSD 0°C to +70°C MAX1489EC/D 0°C to +70°C MAX1489EEPD -40°C to ...
