Abstract
A logical circuit comprises a circuit having a plurality of insulated gate field effect transistors of different channel types and three terminals to which are connected corresponding voltage sources each having a different voltage level, and means for supplying first, second and third logical signals having the maximum and minimum voltage levels of the above-mentioned three different voltage levels to the circuit so that only one current path is always created between an output terminal of the circuit and any one of the three terminals. As a result, the logical circuit can generate an output having three logical levels.
