General Description

The DS7820A and the DS8820A are improved performance

digital line receivers with two completely independent units

fabricated on a single silicon chip. Intended for use with digi-

tal systems connected by twisted pair lines, they have a dif-

ferential input designed to reject large common mode sig-

nals while responding to small differential signals. The output

is directly compatible with TTL or LS integrated circuits.

10% supply voltage variations.

Features

n Operation from a single +5V logic supply

n Input voltage range of 15V

n Strobe low forces output to “1” state

n High input resistance

n Fanout of ten with TTL integrated circuits

n Outputs can be wire OR’ed

n Series 54/74 compatible

The response time can be controlled with an external capaci-

tor to reject input noise spikes. The output state is a logic “1”

for both inputs open. Termination resistors for the twisted

pair line are also included in the circuit. Both the DS7820A

and the DS8820A are specified, worst case, over their full
