DS75150

Dual Line Driver

General Description

The DS75150 is a dual monolithic line driver designed to sat-

isfy the requirements of the standard interface between data

terminal equipment and data communication equipment as

defined by EIA Standard RS-232-C. A rate of 20,000 bits per

second can be transmitted with a full 2500 pF load. Other ap-

plications are in data-transmission systems using relatively

short single lines, in level translators, and for driving MOS

devices. The logic input is compatible with most TTL and LS

families. Operation is from −12V and +12V power supplies.

Features

n Withstands sustained output short-circuit to any low

impedance voltage between −25V and +25V

n 2 µs max transition time through the −3V to +3V

transition region under full 2500 pF load

n Inputs compatible with most TTL and LS families

n Common strobe input

n Inverting output

n Slew rate can be controlled with an external capacitor at

the output

n Standard supply voltages:
