DS9637A
Dual Differential Line Receiver
General Description
The DS9637A is a Schottky dual differential line receiver
which has been specifically designed to satisfy the require-
ments 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 rec-
ommendations. The DS9637A is suitable for use as a line re-
ceiver 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.
