PROBLEM TO BE SOLVED: To solve the problem that there is a pseudo differential circuit as a circuit scheme effectively utilizing the merit of both a CMOS circuit and a differential circuit but when process variation or the like is taken into account, a cross point of positive and negative outputs is not fixed and duty variation of an output waveform also increases. SOLUTION: A semiconductor circuit according to the present invention includes: a first transistor of a first conductivity type which is connected between a first power source and an output terminal and to which an input signal is applied; a second transistor of a second conductivity type connected between a second power source and the output terminal; a third transistor of the second conductivity type connected between the first power source and the output terminal; and a fourth transistor of the first conductivity type connected between the second power source and the output terminal.
