ABSTRACT:
An adjustable integrated circuit output driver circuit is described which has a push-pull output circuit comprised of a pullup and pulldown transistor. A series of parallel transistors are connected to both the pullup and pulldown transistors. The gates of the parallel transistors are selectively controlled to adjust the driver current connected to a data bus line. Adjustable slew rate control circuits are described which are coupled to the pullup and pulldown transistors. Slew rate control circuitry and output control circuitry is provided to selectively adjust the driver circuit either during manufacture or after installation on a data bus. An alternate open-drain adjustable output driver circuit is also described.
