DS78LS120

Dual Differential Line Receiver (Noise Filtering and

Fail-Safe)

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.

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.

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 180

Ω

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.

Input specifications meet or exceed those of the popular

DS7820 line receiver.
