QUAD EIA–422/3 LINE

RECEIVER WITH

THREE–STATE OUTPUTS

Motorola′s Quad EIA–422/3 Receiver features four independent receiver

chains which comply with EIA Standards for the Electrical Characteristics of

Balanced/Unbalanced Voltage Digital Interface Circuits. Receiver outputs

are 74LS compatible, three–state structures which are forced to a high

impedance state when Pin 4 is a Logic “0” and Pin 12 is a Logic “1.” A PNP

device buffers each output control pin to assure minimum loading for either

Logic “1” or Logic “0” inputs. In addition, each receiver chain has internal

hysteresis circuitry to improve noise margin and discourage output instability

for slowly changing input waveforms. A summary of AM26LS32 features

include:
