Abstract
An output circuit of a semiconductor device for suppressing erroneous operation due to potential variations of the power supply line or the ground line. The output circuit comprises an output stage inverter connected between the power supply line and the ground line and a clamping circuit for clamping the voltages applied to the output stage inverter. A large instantaneous current which flows through the output stage inverter during a transition of state is greatly suppressed so that erroneous operation is prevented.
