In the input/output circuit, a circuit section includes power supply terminals and ground terminals. A switching section is switchable between a first state in which a power supply line and a ground line are coupled to one of the power supply terminals and one of the ground terminals and a second state in which the power supply line and the ground line are coupled to the other one of the power supply terminals and the other one of the ground terminals. The circuit section operates as a circuit corresponding to one of an open collector output and an open emitter output in the first state and operates as a circuit corresponding to the other one of the open collector output and the open emitter output in the second state.
