ABSTRACT:
An output circuit protected by an abnormal voltage supplied at an output terminal is disclosed. The output circuit comprises a first switching circuit includes first and second transistors connected in series for providing an output terminal with a first potential therethrough in response to a first logic state of a logic signal, a second switching circuit for providing the output terminal with a second potential in response to a second logic state of the logic signal, and means for making the first and second transistors non-conducting when the first switching circuit is disenabled.
