Description

The DS9639A is a Schottky dual differential line receiver which has been specifically designed to satisfy the requirements 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 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 5.0V power supply and has Schottky TTL compatible outputs. The DS9639A has an operational input common mode range of ±7.0V either differentially or to ground.
