DS78C20/DS88C20

Dual CMOS Compatible Differential Line Receiver

General Description

Features

n Meets requirements of EIA Standards RS-232-C RS-422

The DS78C20 and DS88C20 are high performance, dual dif-

ferential, CMOS compatible line receivers for both balanced

and unbalanced digital data transmission. The inputs are

compatible with EIA and Federal Standards.

and RS-423, and Federal Standards 1020 and 1030

n Input voltage range of 15V (differential or

common-mode)

n Separate strobe input for each receiver

Input specifications meet or exceed those of the popular

DS7820/DS8820 line receiver, and the pinout is identical.

⁄2 V_CCstrobe threshold for CMOS compatibility

n 5k typical input impedance

n 50 mV input hysteresis

n 200 mV input threshold

A response pin is provided for controlling sensitivity to input

noise spikes with an external capacitor. Each receiver in-

cludes a 180Ω terminating resistor, which may be used op-

tionally on twisted pair lines. The DS78C20 is specified over

a −55˚C to +125˚C operating temperature range, and the

DS88C20 over a 0˚C to +70˚C range.

n Operation voltage range 4.5V to 15V

n DS7830/DS8830 recommended driver
