Abstract
An input circuit includes a gate circuit receiving an output power supply voltage that determines the logic level of an input signal or a comparison circuit receiving an input signal and a reference voltage depending on the output power supply voltage supplied from a pad different from a power supply pad for an output circuit. Even if the output power supply voltage varies to cause the input signal to change, whether the input signal is at H level or L level can accurately be determined and an internal signal is generated correctly
