Abstract
A compact integrated logic circuit having an inverter transistor and several coupling diodes adjoining the collector region of said transistor. Current is applied to the base of the transistor which forms the signal input. The inverter transistor has additional means by which an effective complementary auxiliary transistor is incorporated which dissipates a considerable part of the base current in the case the inverter transistor is overdriven so that the charge storage in the inverter transistor is restricted and controlled and by which a Schottky clamp diode across the base-collector junction of the inverter transistor can be avoided.
