  • Driver circuit
    Patent number: 6720803
    Abstract: A technique includes, in response to a first signal transitioning to a first logic state and first drive circuit being deactivated, activating a second drive circuit to provide a second signal. In response to the second drive circuit being deactivated and the first signal transitioning to a second logic state that is different from the first logic state, the first drive circuit is activated to provide the second signal.
