DS78LS120

Dual Differential Line Receiver (Noise Filtering and

Fail-Safe)

Input specifications meet or exceed those of the popular

DS7820 line receiver.

General Description

The DS78LS120 is a high performance, dual differential, TTL

compatible line receiver for both balanced and unbalanced

digital data transmission. The inputs are compatible with

EIA, Federal and MIL standards.

Features

n Meets EIA standards RS232-C, RS422 and RS423,

Federal Standards 1020, 1030 and MIL-188-114

n Input voltage range of 15V (differential or

common-mode)

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 Separate strobe input for each receiver

n 5k typical input impedance

n Optional 180Ω termination resistor

n 50mV input hysteresis

n 200mV input threshold

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 an optional 180Ω

terminating resistor and the output gate contains a logic

strobe for time discrimination. The DS78LS120 is specified

over a −55˚C to +125˚C temperature range.
