CMOS circuit having shoot through current control

摘要

A complemenary MOS integrated circuit comprising an output circuit and a pre-output circuit, which is capable of reducing a penetration current which occurs upon switching of transistors in the output circuit, to thereby suppress an occurrence of spike noises in an output signal. The pre-output circuit comprises MOS transistors constituting an analog switch, "on-resistances" of which are utilized as a resistor, and MOS transistor gates. A series circuit of the analog switch and the gates are coupled in series with a power source.
