Abstract
An output circuit that outputs a voltage signal to a circuit having a power supply higher than that of the output circuit, wherein the voltage signal quickly increases to the potential level of the power supply of the output circuit. An input/output circuit includes the output circuit, and an input circuit that receives a voltage signal from a circuit having a power supply higher than that of the output circuit, and forwards the voltage signal to a circuit having a power supply identical to that of the input circuit. The potential level of the forwarded signal is the voltage of the power supply of the input circuit.
