Abstract
A three-input exclusive NOR circuit having three signal paths provided between three input terminals and three-input exclusive OR node, each of the signal paths having two first conduction type transistors connected in series, said two first conduction type transistors being in conductive state when a low level signal is applied to the gate terminal of the transistor; and three signal paths provided between three input terminal and three-input exclusive OR node, each of the signal paths having two second type transistors being in conductive state when a high level signal is applied to the gate terminal of the transistors, wherein two input signals other than the input signal to a signal path is respectively supplied to the gate terminals of two of the first and second conduction type transistors.
