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.
