DS3487 Quad TRI-STATE Line Driver May 1998 DS3487 Quad TRI-STATE ® Line Driver General Description 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.
