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.

NOTES: 1.All currents into device pins are shown as positive, out of device pins are negative. All voltages referenced to ground unless otherwise noted.

2.Differential input threshold voltage and guaranteed output levels are done simultaneously for worst case.

3.Refer to EIA–422/3 for exact conditions. Input balance and guaranteed output levels are done simultaneously for worst case.

4.Only one output at a time should be shorted.
