DESCRIPTION
The UC5180C is an octal line receiver designed to meet a wide range
of digital communications requirements as outlined in EIA standards
EIA232E, EIA423A, EIA422A, and CCITT V.10, V.11, V.28, X.26, and
X.27. The UC5180C includes an input noise filter and is intended for
applications employing data rates up to 200 KBPS. A failsafe function
allows these devices to "fail" to a known state under a wide variety of
fault conditions at the inputs.
