PROBLEM TO BE SOLVED: To reduce power consumption while ensuring the amplitude of an output signal of an output buffer. SOLUTION: A clamp transistor M3 is inserted in series between a P-channel field effect transistor M1 and an N-channel field effect transistor M2, and an intermediate level between a high potential supplied to a source of the P-channel field effect transistor M1 and a low potential supplied to a source of the N-channel field effect transistor M2 is inputted into a gate of the clamp transistor M3, thereby clamping a drain potential of the N-channel field effect transistor M2.
