Abstract

In an output circuit for use in a semiconductor IC comprising a CMOS transistors constituting an output buffer, a transfer gate of CMOS structure is connected between the gates of the CMOS transistors as a resistive element. The transfer gate reduces the changes in the gate potentials of output transistors, which occur when logic inputs are supplied to the gates of the output control transistors. Hence, the deformation of the output waveform, which has resulted from the through currents flowing through the output transistors, is minimized.
