A CMOS circuit prevents feedthrough current and has a small-scaled circuit constitution. An output stage has a P-channel MOS transistor and an N-channel MOS transistor with drains connected to each other to form an output terminal and gates respectively connected to output terminals of first and second series circuits. The first and second series circuits control supply of power and each includes an N-channel MOS transistor and a P-channel MOS transistor with drains connected together to form the output terminal and gates connected together to form an input terminal. A delay circuit receives an input signal and produces a delayed input signal which drives the input terminals of the first and second series circuits. P-channel and N-channel MOS transistors control power potentials applied to sources of the respective P-channel and N-channel MOS transistors of the second and first series circuits and are driven by the input signal which is applied to their gates. The P-channel and N-channel MOS transistors are thereby controlled such that current feedthrough is prevented.
