ABSTRACT:
A multiplexor having a multiplexor control input terminal for selectively providing one of a plurality of conductor voltage levels to a conductor. The multiplexor includes a first switch, which is coupled to the conductor, for providing a first conductor voltage level to the conductor. A second switch is also included and coupled to the conductor for providing a second conductor voltage level to the conductor. To provide a selective discharge path for the conductor during switching, the multiplexor further includes a third switch coupled to the conductor. A discharge circuit is also provided and coupled to the conductor and the third switch for sensing the voltage level of the conductor to turn on the third switch as necessary at the early stage of switching among conductor voltage levels.
