Abstract
The invention provides a logic circuit which has a sufficient load driving capacity even in its operation with a low power supply voltage and can operate at a high speed. In a next stage to a differential circuit having an output stage for which an emitter followers are used, a folding circuit in which a pair of transistors of a diode connection are used to raise the signal level of differential outputs of the differential circuit.
