A constant current source circuit includes one end connected to a second node as sources of third and fourth transistors, and the other end connected to a second power supply node that supplies a second voltage different from a first voltage. The clamp circuit is configured to form a current path between the second node and the second power supply node. It adjusts the potential of the second node to a certain potential when a first external input signal is switched from a first state to a second state. |
