Abstract
An integrated circuit includes an output driver circuit having a plurality of output driver devices connected in a parallel arrangement and an output driver controller that is capable of individually controlling the conducting states of the output driver devices. In at least one embodiment, the controller is capable of achieving any of a plurality of different fall times (and/or rise times) in an output signal by appropriately controlling the conducting states of the output devices if a change in the state of the output signal is desired, in some implementations, the controller is capable of achieving different waveshapes during rising and/or failing edges of an output signal.
