A differential logic gate providing complimentary input and complimentary output operation. Transistors (50,52) provide the differential input and emitter follower transistors (54,62) provide the complimentary outputs. Enhanced output high logic levels are enabled by PNP transistors (40,46). PNP transistors (40,46) supply base current drive to transistors (54,62) which boosts the output logic high voltage values presented at terminals (Q,Q-compliment) by reducing collector resistor voltage drop across resistors (42,44). PNP transistors (40,46) remain in their respective conductive states due to voltage regulators (38,48) to provide for faster operation.
