DS78C120

Dual CMOS Compatible Differential Line Receiver

General Description

Features

n Full compatibility with EIA Standards RS232-C, RS422

and RS423, Federal Standards 1020, 1030 and

MIL-188-114

The DS78C120 is a high performance, dual differential,

CMOS compatible line receiver for both balanced and unbal-

anced digital data transmission. The inputs are compatible

with EIA, Federal and MIL standards.

n Input voltage range of 15V (differential or

common-mode)

Input specifications meet or exceed those of the popular

DS7820 line receiver.

n Separate strobe input for each receiver

n 1/2 V_CCstrobe threshold for CMOS compatibility

n 5k typical input impedance

n 50 mV input hysteresis

The line receiver will discriminate a 200 mV input signal

over a common-mode range of 10V and a 300 mV signal

over a range of 15V.

n 200 mV input threshold

n Operation voltage range 4.5V to 15V

n Separate fail-safe mode

Circuit features include hysteresis and response control for

applications where controlled rise and fall times and/or high

frequency noise rejection are desirable. Threshold offset

control is provided for fail-safe detection, should the input be

open or short. Each receiver includes a 180Ω terminating re-

sistor and the output gate contains a logic strobe for time dis-

crimination. The DS78C120 is specified over a −55˚C to

+125˚C temperature range.
