Abstract

A flip-flop circuit is constituted of two latch circuits of the same structure that are cascaded. The latch circuits each includes an inverter formed of a P channel transistor and an N channel transistor, an N channel transistor connected between a common node and a ground node, and two data input/output terminals. Two kinds of clock signals supplied to gates of N channel transistors are complementary to each other.
