ABSTRACT:
A semiconductor integrated circuit that handles the input/output of a signal with an external circuit. The circuit includes a transistor transmitting a signal between the external circuit and an internal circuit with a drain/source therebetween at a given gate voltage. A first gate voltage supply circuit supplies a voltage at the gate of the transistor when supplied with a first power voltage at a first level of a control signal. A second gate voltage supply circuit supplies a voltage at the gate of the transistor when supplied with a second power voltage that is lower than the first power voltage at a second level of a control signal.
