DS78C120/DS88C120 Dual CMOS Compatible

Differential Line Receiver

General Description

Features

Full compatibility with EIA Standards RS232-C, RS422

and RS423, Federal Standards 1020, 1030 and MIL-

188-114

The DS78C120 and DS88C120 are high performance, dual

differential, CMOS compatible line receivers for both bal-

anced and unbalanced digital data transmission. The inputs

are compatible with EIA, Federal and MIL standards.

Input voltage range of 15V (differential or common-

mode)

Input specifications meet or exceed those of the popular

DS7820/DS8820 line receiver.

Separate strobe input for each receiver

1/2 V

strobe threshold for CMOS compatibility

The line receiver will discriminate a 200 mV input signal

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

5k typical input impedance

50 mV input hysteresis

200 mV input threshold

nal 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 a 180X terminating

resistor and the output gate contains a logic strobe for time

Operation voltage range

Separate fail-safe mode

4.5V to 15V

discrimination. The DS78C120 is specified over a 55 C to

125 C temperature range and the DS88C120 from 0 C to

70 C.
