US Patent 7498846 Power efficient multiplexer

A power efficient multiplexer. In accordance with a first embodiment of the present invention, a power efficient multiplexer comprises a transmission gate structure for selectively passing one of a plurality of input signals and a stacked inverter circuit for inverting the one of a plurality of input signals. Both the stacked inverter and the transmission gate provide beneficial reductions in static power consumption in comparison to conventional multiplexer designs.
