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 recom-
mendations. 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 sin-
gle 5V power supply and has Schottky TTL compatible out-
puts. The DS9637A has an operational input common mode
range of ±7V either differentially or to ground.
