ABSTRACT:
A low driving voltage operation logic circuit responsive to a power source voltage applied between a pair of power source terminals for modifying an input signal according to a predetermined logic pattern. The logic circuit includes an input control circuit having a plurality of input transistors for generating a pair of control signals, each having a level opposite to the other, in response to the input signal and a differential circuit having a plurality of paired transistors for dividing the frequency of the control signals, the input transistors each having an emitter area substantially larger than the emitter area of each paired transistor and the logic circuit including only a single base to emitter junction corresponding to each input transistor between the power source terminals.
