Abstract
An output circuit having the output taken between a pull-up output transistor and a pull-down output transistor connected in series for conducting current alternatively. Separate pull-up and pull-down driver circuits are controlled by a common input signal. The pull-down driver circuit is supplied by a pull-down current source, and a diode is connected from the point between the pull-down driver transistor and pull-down current source to the output node. The effect of a large node capacitance is reduced by the diode, which conducts current from the pull-down current source to any output load capacitance to raise the output voltage more rapidly when the pull-down driver circuit is cut off.
