ABSTRACT:
A semiconductor integrated circuit includes an input buffer circuit that has an input terminal connected to an external signal input pad. A level-setting resistor is arranged between the input buffer circuit and a reference potential terminal having a reference potential, for holding the input terminal at the reference potential. The level-setting resistor comprises a transistor that is supplied with a control signal, and set to an off state by the control signal when the external signal input pad is in a predetermined potential state.
