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-
erational input common mode range of ±7.0V either differen-
tially or to ground.
