ABSTRACT:
According to an exemplary embodiment, an output driver circuit includes a pre-conditioning circuit. The output driver circuit further includes a timing control circuit coupled to an output of the pre-conditioning circuit, where the timing control circuit has a first state and a second state. The output driver circuit further includes a first transistor having a first terminal coupled to the timing control circuit and a second transistor having a first terminal coupled to the timing control circuit. When the timing control circuit is in the first state the pre-conditioning circuit output is coupled to the first terminal of the first transistor and not coupled to the first terminal of the second transistor, and when the timing control circuit is in the second state the pre-conditioning circuit output is coupled to the first terminal of the second transistor and not coupled to the first terminal of the second transistor.
