The source of a p-channel MOSFET of a level conversion unit is connected to a supply terminal which receives supply voltage VDD. The drain is connected to an output node NO and the gate is connected to an input node I 2 . The source of a n-channel MOSFET is connected to an input node I 2 , the drain is connected to the output node NO and the gate is connected to the supply terminal which receives the supply voltage VDD. Input signals CLK 1 and CLK 2 change complementarily and difference of voltage between the high level and low level of the signals is smaller than difference between the supply voltage VDD and the ground voltage.
