High-Speed Schottky Circuitry
8-Pin Dual-In-Line Packages
Designed to Be Interchangeable With
National DS9639AC
description
The uA9639C is a dual differential line receiver
designed to meet ANSI Standards EIA/TIA-422-B
and EIA/TIA-423-B and ITU Recommendations
V.10 and V.11. It utilizes Schottky circuitry and
has TTL-compatible outputs. The inputs are
compatible with either a single-ended or a
differential-line system. This device operates from
a single 5-V power supply and is supplied in an
8-pin, dual-in-line package.
The uA9639C is characterized for operation from
0
°
C to 70
°
