In a semiconductor integral circuit having a transistor or an inverter, a leak current of the transistor or a through current of the inverter, respectively, or the like is reduced. The semiconductor integral circuit has an analog circuit which changes linearly the voltage of an input signal and causes the amount of a current flowing through the analog circuit to change in accordance with the change in the voltage of the input signal. The semiconductor integral circuit also has a logic circuit to which an input signal having a first or second voltage is input. This logic circuit outputs an output signal having the first or second voltage in response to the first or second voltage of the input signal. The absolute value of the threshold value of the MOS transistor of the analog circuit is set smaller than the absolute value of the threshold value of the MOS transistor of the logic circuit.
