Motorolais Quad EIA–422 Driver features four independent driver chains
which comply with EIA Standards for the Electrical Characteristics of
Balanced Voltage Digital Interface Circuits. The outputs are three–state
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
