Abstract
An output circuit includes a driver circuit and a node control circuit. The driver circuit includes a first transistor and a second transistor. The first transistor includes one end coupled to an external terminal and the other end coupled to a first node. The second transistor includes one end coupled to the first node and the other end coupled to a wiring that is supplied with a power supply voltage. When the first transistor and the second transistor are deactivated, the node control circuit supplies a node control signal based on a voltage of the external terminal to the first node.
