Abstract
An output circuit of a push-pull type is disclosed. The output circuit includes first and second transistors connected in series, means responsive to a data signal for producing true and complementary signals of the data signal, and means for supplying the true and complementary signals to the first and second transistors. The output circuit further includes means for generating one-shot pulse at a transition time when the true and complementary signals are changed in their logic levels and means response to said one-shot pulse for turning said first and second transistors OFF. A large current flowing at the transition time is thereby prevented.
