Abstract

An output circuit has a power supply terminal, a ground terminal, and an output terminal for connection with an external power supply voltage. The output circuit generates a voltage through the output terminal within a certain potential range. This potential range is determined by a potential of the power supply terminal and a potential of the ground terminal. The output circuit includes a first transistor having one main electrode connected to the power supply terminal and the other main electrode connected to the output terminal. The output circuit also includes a second transistor having one main electrode connected to a control electrode of the first transistor and the other main electrode connected to the output terminal. The output circuit also includes an earth circuit connected to the control electrode of the first transistor for removing charges stored thereon. The second transistor is turned on when the voltage of the output terminal is beyond the above-mentioned potential range. The first transistor is turned off as the voltage of the output terminal is introduced to the control electrode of the first transistor when the second transistor is turned on.
