ABSTRACT:
The switch of this invention has two conduction terminals and basically consists of the parallel coupling, across the two conduction terminals, of a first N-channel MOS transistor and second P-channel MOS transistor. The first MOS transistor will be conducting when the signal applied to the conduction terminals has a first polarity, and the second MOS transistor will be conducting when the signal applied to the conduction terminals has a second polarity. Advantageously, if two unidirectional conduction circuit elements are respectively connected in series with the main conduction paths of the two MOS transistors, the drain/body junctions of the latter will never be conducting regardless of the way the switch is connected.
