PROBLEM TO BE SOLVED: To obtain low power consumption while operation speed is kept unchanged. SOLUTION: In a toggle type flip-flop circuit (TFF), each signal of an output terminal (out) and an inverse output terminal (outb) latched at latch portions 22A, 22B are converted through a clock (ck) and an inverse clock (ckb). A load transistor 21-11 connected to the output terminal (out) is subjected to continuity control by a signal from the inverse output terminal (outb), and a load transistor 21-12 connected to the inverse output terminal (outb) is subjected to continuity control by a signal from the output terminal (out). In this way, the low power consumption is ensured while rising speed of H level signal is kept unchanged. COPYRIGHT: (C)2007,JPO&INPIT
