Abstract
A structure for and method of operating a transition-controlled off-chip driver is disclosed. Turn-on of output pulling devices is controlled, while turn-off is uncontrolled. An AC voltage reference circuit dissipating essentially zero DC power provides a reference voltage for control during transition. Turn-on control dissipates during transition, and ends when transition is complete without the use of output feedback.
