Abstract:
A multi-valued logical circuit outputting first to (Nâˆ’1)th power supply potentials, where N is an integer not less than 3, and a reference potential to an output node in response to first to Nth signals, respectively, the multi-valued logical circuit comprising:a first transistor of a first conductive type provided to correspond to each power supply potential, having both a first electrode and a substrate electrode receiving the corresponding power supply potential, and becoming conductive in response to input of the corresponding signal; a second transistor of the first conductive type provided to correspond to each power supply potential, having a first electrode connected to a second electrode of said first transistor, having both a second electrode and a substrate electrode connected to said output node, and becoming conductive in response to the input of the corresponding signal; and a third transistor of a second conductive type having a first electrode connected to said output node, having a second electrode receiving said reference potential, and becoming conductive in response to the input of said Nth signal.
