ABSTRACT:
It is an object to enlarge the logical amplitude of an output signal of a flip-flop circuit with a suppressed, low power-supply voltage to reduce the possibility of occurrence of malfunction. A signal outputted from a differential amplification portion is converted in an internal level converting circuit and fed back to bases of transistors of a slave latch. With input signals having a high level at 0.5 V, the internal level converting circuit performs conversion to provide output signals having a high level at 0.25 V to prevent a current flowing between a collector and a base of the transistors.
