| 摘要 |
The switch of this invention has two conduction terminals (TA,TB) and basically consists of the parallel coupling, across the two conduction terminals (TA,TB), of a first N-channel MOS transistor (M1L) and second P-channel MOS transistor (M1R). 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 (D1L,D1R) are respectively connected in series with the main conduction paths of the two MOS transistors (M1L,M1R), the drain/body junctions (DI1L,DI1R) of the latter will never be conducting regardless of the way the switch is connected. <IMAGE>
