1 Order this document by MC3487/D Motorolas Quad EIA422 Driver features four independent driver chains which comply with EIA Standards for the Electrical Characteristics of Balanced Voltage Digital Interface Circuits. The outputs are threestate structures which are forced to a high impedance state when the appropriate output control pin reaches a logic zero condition. All input pins are PNP buffered to minimize input loading for either logic one or logic zero inputs. In addition, internal circuitry assures a high impedance output state during the transition between power up and power down. A summary of MC3487 features include: Four Independent Driver Chains ThreeState s PNP High Impedance s (PIA Compatible) Fast Propagation Times (Typical 15 ns) TTL Compatible Single 5.
