ABSTRACT:
In a voltage selector circuit, a plurality of supply voltages are respectively supplied to a plurality of switching elements formed of MOS transistors. The plurality of switching elements are turned on and off according to the voltage levels of input signals supplied thereto, and a voltage waveform signal corresponding to one selected among the supply voltages is taken out from a common output terminal. The substrate electrode of a specified one of the switching elements is supplied with a corresponding supply voltage as the substrate voltage in response to a voltage change of the voltage waveform signal taken out selectively, thereby reducing power loss in the circuit.
