DS3486

Quad RS-422, RS-423 Line Receiver

General Description

Features

National's quad RS-422, RS-423 receiver features four inde-

pendent receivers which comply with EIA Standards for the

electrical characteristics of balanced/unbalanced voltage dig-

ital interface circuits. Receiver outputs are 74LS compatible,

TRI-STATE^®structures which are forced to a high impedance

state when the appropriate output control pin reaches a logic

zero condition. A PNP device buffers each output control pin

to assure minimum loading for either logic one or logic zero

inputs. In addition, each receiver has internal hysteresis cir-

cuitry to improve noise margin and discourage output insta-

bility for slowly changing input waveforms.

Four independent receivers
