A low-power, high-speed flip-flop circuit is provided that has a simplified, smaller circuit configuration. A flip-flop comprises two latch hold circuits composed of transistors (B1-B4) and transistors (B5-B8), respectively; and a clock-input differential circuit composed of transistors (B9-B12). With clock inputs (CP) and (CN) being high and low, respectively, transistors (B9, B10) turn on, and the current from a constant current source (12) turns transistor (B2, B3) off. Similarly, transistors (B5, B8) are also turned off, causing the second latch hold circuit to be in hold state. With clock inputs (CP) and (CN) being low and high, respectively, the states of the first and second latch hold circuits are switched, resulting in flip-flop operation.
