ABSTRACT:
A level conversion circuit that converts a signal outputted from a second internal circuit receiving a first power supply voltage to a signal of a level of a second power supply voltage having a voltage level different than the first power supply voltage to apply its output signal to a first internal circuit, is provided with a mechanism for cutting off a path passing a through current in the level conversion circuit when the first power supply voltage is cut off.
