ABSTRACT:
This invention discloses an output circuit in an integrated circuit. This invention includes first and second MOS transistors and a drive and control circuit. The first and second MOS transistors are connected in series between Vcc and Vss power source nodes, and receive complementary signals, respectively. When one of the transistors is OFF, and the other transistor is turned off from an ON state, the drive and control circuit moderately decreases a gate potential of the other transistor to a level at which a transconductance of the transistor which is turned off from an ON state is decreased to some extent. Thereafter, the drive and control circuit decreases the gate potential to a level at which the transconductance is sufficiently decreased.
