ABSTRACT:
A logic circuit includes a first and a second bipolar transistor forming a signal output circuit; first and a second MOS transistor circuits each for performing a specified logic operation with the input signal, and making or breaking connection between the collector and the base of the first and second bipolar transistors, respectively, in reverse relation to each other. A third MOS transistor circuit is connected between the first bipolar transistor and a ground potential point, and second MOS transistor is connected between the base and the emitter of the first MOS. A control circuit is provided for causing the first and second MOS transistors to turn ON or OFF later than the turn-ON of turn-OFF of the first and second MOS transistor circuits. Further, a third MOS transistor caused to turn ON or OFF by the control circuit is provided between the base of the first bipolar transistor and the third MOS transistor.
