Abstract
An output circuit includes a first output transistor disposed between a higher-potential power supply terminal and an external output terminal, a current flowing from the source of the first output transistor to the drain thereof being controlled on the basis of an external input signal; a second output transistor disposed between a lower-potential power supply terminal and the external output terminal, a current flowing from the source of the second output transistor to the drain thereof being controlled on the basis of an external input signal; and a clamping transistor having a first terminal and a control terminal, the first terminal and the control terminal being coupled to the gate of the first output transistor, and a second terminal coupled to the drain of the first output transistor.
