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 “fail” to a known state under a

wide variety of fault conditions at the inputs.
