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.

APPLICATIONS INFORMATION
Failsafe Operation
These devices provide a failsafe operating mode to
guard against input fault conditions as defined in
EIA422A and EIA423A standards. These fault condi-
tions are (1) drive in power-off condition, (2) receiver not
interconnected with driver, (3) open-circuited intercon-
necting cable, and (4) short-circuited interconnecting
cable. If one of these four fault conditions occurs at the
inputs of a receiver, then the output of that receiver is
driven to a known logic level. The receiver is pro-
grammed by connecting the failsafe input to VCC or
ground. A connection to VCC provides a logic "1" output
EIA232E/V.28 / EIA423A/V.10 DATA TRANSMISSION
under fault conditions, while a connection to ground
provides a logic "0". There are two failsafe pins (FS1
and FS2) on the UC5180C where each provides com-
mon failsafe control for four receivers.
Input Filtering (UC5180C)
The UC5180C has input filtering for additional noise re-
jection. This filtering is a function of both signal level
and frequency. For the specified input (5.5 MHz at ±500
mV) the input stage filter attenuates the signal such that
the output stage threshold levels are not exceeded and
no change of state occurs at the output.
