A semiconductor integrated circuit includes a first logic circuit to which a first power supply voltage is applied and which outputs a first signal, a first level conversion circuit to which the first power supply voltage and a second power supply voltage having an amplitude of second voltage level different from the first power supply voltage are supplied and which outputs a second signal, a second logic circuit to which the second power supply voltage is applied and which outputs a third signal, and a second level conversion circuit which is connected between the first and second logic circuits, to which the first and second power supply voltages are applied, and which level-converts the third signal of the second voltage level output from the second logic circuit to the first voltage level and outputs a fourth signal.
