DESCRIPTION
The DS3487 quad RS-422 driver features four
independent drivers which comply with EIA Standards
for the electrical characteristics of balanced voltage
digital interface circuits. The outputs are TRI-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.
