The invention provides a semiconductor circuit which can accept signals of various levels and operate at a high speed with low power dissipation. The semiconductor circuit includes a PMOS differential circuit having two inputs one of which is connected to a first input terminal and the other of which is connected to a second input terminal, an NMOS differential circuit having two inputs one of which is connected to the first input terminal and the other of which is connected to the second input terminal, and an output circuit operable in response to differential outputs of the PMOS differential circuit and the NMOS differential circuit for preventing, when a current path is formed between an output terminal and a power supply terminal, formation of a current path between a ground terminal and the output terminal, but preventing, when a current path is formed between the output terminal and the ground terminal, formation of a current path between the power supply terminal and the output terminal.
