A semiconductor integrated circuit is provided that operates with a first power supply voltage and a second power supply voltage that is higher than the first power supply voltage. The circuit comprises at least one transistor that drops the second power supply voltage, a first-stage level shifter operated with a voltage supplied from the second power supply voltage via at least one transistor and shifting a level of a signal input from a circuit that is operated with the first power supply voltage, and a second-stage level shifter operated with the second power supply voltage and shifting a level of a signal input from at least one level shifter.
