DESCRIPTION

The DS9637A is a Schottky dual differential line

receiver which has been specifically designed to

satisfy the requirements of EIA Standards RS-422

and RS-423. In addition, the DS9637A satisfies the

requirements of MIL-STD 188-114 and is compatible

with the International Standard CCITT recommendations. The DS9637A is suitable for use

as a line receiver in digital data systems, using either

single ended or differential, unipolar or bipolar

transmission. It requires a single 5V power supply

and has Schottky TTL compatible outputs. The

DS9637A has an operational input common mode

range of ±7V either differentially or to ground.
