DS9639A

Dual Differential Line Receiver

General Description

The DS9639A is a Schottky dual differential line receiver

which has been specifically designed to satisfy the require-

ments of EIA Standards RS-422, RS-423 and RS-232C. In

addition, the DS9639A satisfies the requirements of

MIL-STD 188-114 and is compatible with the International

Standard CCITT recommendations. The DS9639A is suit-

able for use as a line receiver in digital data systems, using

either single ended or differential, unipolar or bipolar trans-

mission. It requires a single 5.0V power supply and has

Schottky TTL compatible outputs. The DS9639A has an op-

tially or to ground.
