PROBLEM TO BE SOLVED: To obtain an integrated circuit device that effectively interrupts supply of power in the power-down mode. SOLUTION: The integrated circuit device is provided with a NAND circuit ND1 that receives an output signal from a NAND circuit ND2 connecting to power supplies 18, 19, a PMOS transistor(TR) 26 whose source connects to the power supply 18, whose back-gate connects to the power supply 19, and whose gate connects to the NAND circuit ND1, and an NMOS TR 27 whose back-gate connects to a ground power supply 20, whose gate connects to a NOR circuit NR1 and whose source connects to the drain of the PMOS TR 26.
