QUAD EIA–422/3 LINE
Motorola′s Quad EIA–422/3 Receiver features four independent receiver RECEIVER WITH
chains which comply with EIA Standards for the Electrical Characteristics of
Balanced/Unbalanced Voltage Digital Interface Circuits. Receiver outputs THREE–STATE 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 SEMICONDUCTOR
device buffers each output control pin to assure minimum loading for either TECHNICAL DATA
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
