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:

•Four Independent Receiver Chains

•Three–State Outputs

•High Impedance Output Control Inputs

(PIA Compatible)

•Internal Hysteresis – 30 mV (Typical) @ Zero Volts Common Mode

•Fast Propagation Times – 25 ns (Typical)

•TTL Compatible

•Single 5.0 V Supply Voltage

•Fail–Safe Input–Output Relationship. Output Always High When Inputs

Are Open, Terminated or Shorted

•6.0 k Minimum Input Impedance

* Note that the surface mount MC26LS32D device uses the same die as in the plastic DIP

*AM26LS32DC device, but with an MC prefix to prevent confusion with the package suffix.
