National’s 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.
