ABSTRACT:
An output circuit which is provided with an integrated circuit composed of a PNP transistor and an NPN transistor of which the base is connected to the collector of the PNP transistor, a voltage source for supplying an electric potential to the emitter of the PNP transistor and voltage dropping means provided outside the integrated circuit for making the electric potential supplied to the collector of the NPN transistor less than the electric potential of the voltage source. Thereby, an electric potential supplied to the NPN transistor can be decreased because a voltage drop is caused by an element provided outside the integrated circuit. Thus, power consumption in the NPN transistor can be decreased. Namely, power consumed in the integrated circuit can be reduced. Consequently, high packaging density of the integrated circuit can be achieved and provision of multiple channels in the integrated circuit can be realized.
