DESCRIPTION
The UC5181C is an octal line receiver designed to meet a wide range
of digital communications requirements as outlined in EIA standards
EIA232E, EIA422A, EIA423A and CCITT V.10, V.11, V.28, X.26, and
X.27. The UC5181C is similar to the UC5180C, but without the input
filtering. Thus, it covers the entire range of data rates up to 10MBPS. A
failsafe function allows these devices to 鈥渇ail鈥?to a known state under a
wide variety of fault conditions at the inputs.
