Features, Applications

The MAX1488E quad, low-power line driver is designed for EIA/TIA-232, EIA/TIA-562, and CCITT V.28 communications in harsh environments. Each transmitter output is protected against 15kV electrostatic discharge (ESD) shocks. The inputs are TTL and CMOS compatible with minimal loading. The outputs feature internally controlled slew-rate limiting and current limiting. This device has a guaranteed 120kbps data rate. Powersupply current is less than 180A over to 13.2V supply voltage range. The MAX1488E is pin compatible with the SN75C188, DS1488, and It is available in 14-pin plastic DIP and SO packages.

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 85A Supply Current from IEE or ICC o Guaranteed 120kbps Data Rate o No External Capacitors Required for Slew-Rate Limiting o Pin Compatible with SN75C188, DS1488, and DS14C88

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
