Abstract
A circuit for presetting the voltage of an output terminal connected to an external load, where the output terminal receives either a high or a low voltage level state for output to the load during a data cycle, includes a voltage detector connected to the output terminal for sensing the voltage level at the output terminal at the end of the data cycle to determine whether the voltage level is at a high or a low voltage level state. A driver is connected to the voltage sensor for driving the voltage level at the output terminal prior to the start of a subsequent data cycle toward the opposite voltage state to a mid-level, as determined by the prior voltage state sensed by the voltage detector.
