Order this document by AM26LS32/D 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.

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.
