1 / 8 page _______________General Description The MAX1488E quad, low-power line driver is designed for EIA/TIA-232, EIA/TIA-562, and CCITT V.28 commu- nications in harsh environments. Each transmitter out- put is protected against ±15kV electrostatic discharge (ESD) shocks. The inputs are TTL and CMOS compati- ble with minimal loading. The outputs feature internally controlled slew-rate limiting and current limiting. This device has a guaranteed 120kbps data rate. Power- supply current is less than 180µA over a ±4.5V to ±13.2V supply voltage range. The MAX1488E is pin compatible with the MC1488, MC14C88, SN75188, SN75C188, DS1488, and DS14C88. It is available in 14-pin plastic DIP and SO packages. ________________________Applications PC Motherboards Modems Interface Data Terminal Equipment (DTE) with Data Circuit-Terminating Equipment (DCE) Equipment Meeting IEC1000-4-2 (formerly IEC801-2) or ±15kV ESD Protection ____________________________Features o ESD Protection: ±15kV—Human Body Model ±6kV—IEC801-2, Contact Discharge ±15kV—IEC801-2, Air-Gap Discharge o Latchup Free, Even During an ESD Event o Low 85µA Supply Current from IEE or ICC o Guaranteed 120kbps Data Rate o No External Capacitors Required for Slew-Rate Limiting o Pin Compatible with MC1488, MC14C88, SN75188, SN75C188, DS1488, and DS14C88 ±15kV ESD-Protected, Quad, Low-Power RS-232 Line Driver ________________________________________________________________ Maxim Integrated Products 1 14 13 12 11 10 9 8 1 2 3 4 5 6 7 VCC INPUT D1 INPUT D2 OUTPUT D INPUT C1 INPUT C2 OUTPUT C VEE INPUT A OUTPUT A INPUT B1 INPUT B2 OUTPUT B GND TOP VIEW MAX1488E DIP/SO __________________Pin Configuration INTERCONNECTING CABLE SIGNAL GROUND TTL/CMOS LOGIC PC MOTHERBOARD (DTE) MODEM (DCE) TTL/CMOS LOGIC 1⁄4 MAX1488E 1⁄4 MAX1489E 1⁄4 MAX1489E 1⁄4 MAX1488E __________Typical Operating Circuit Call toll free 1-800-998-8800 for free samples or literature. 19-2403; Rev 0; 8/95 PART MAX1488ECPD MAX1488ECSD MAX1488EC/D 0°C to +70°C 0°C to +70°C 0°C to +70°C TEMP.
