1 Order this document by A26LS32/D otorola s Quad EIA422/3 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, threestate 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 A26LS32 features include: Four Independent Receiver Chains ThreeState s High Impedance s (PIA Compatible) Internal Hysteresis mv Zero Volts Common ode Fast Propagation Times 25 ns (Typical) TTL Compatible Single 5.
