Abstract

PURPOSE:To prevent current consumption in a fast operation from being increased by providing a PMOS transistor whose gate electrode is connected to an input terminal, whose source electrode to the cathode side terminal of a diode, and whose drain electrode to an output terminal. CONSTITUTION:The gate electrode of the PMOS transistor 4 is connected to the input terminal 1, and the source electrode to the cathode side terminal of the diode 3, and the drain electrode to the output terminal 5. Meanwhile, the gate electrode of an NMOS transistor 6 is connected to the terminal 1, and the source electrode to the anode side terminal of the diode 7, and the drain electrode to the terminal 5. In such a constitution, assuming the potential of a negative power source 8 as 0 and that of a positive power source as VDD, the voltage of the terminal 5 goes to a value less than the VDD by the voltage drop of the diode 3 when the voltage of the terminal 1 is VDD. Also, when the voltage of the terminal 1 is 0, the voltage of the terminal 1 goes to the value larger than 0 by the voltage drop of the diode 3, which reduces the amplitude of the terminal 5, Therefore, it is possible to prevent the current consumption from being increased even in the fast operation.
