摘要： 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 (11) having an output stage for which an emitter followers (Q13, Q14) are used, a folding circuit (12) in which a pair of transistors (Q15, Q16) of a diode connection are used to raise the signal level of differential outputs of the differential circuit (11).
