PROBLEM TO BE SOLVED: To provide a flip-flop circuit which has a reset function and causes no leakage path. SOLUTION: When a reset signal becomes high level, PMOS transistor PT5 is cut off and NMOS transistor NT6 is turned on. Consequently, a node N2 and a node N3 are separated by the PMOS transistor PT5 while electric charge is discharged from a node N3 via the NMOS transistor NT6, and thereby the node N3 becomes low level. Accordingly, PMOS transistor PT4 is turned on NMOS transistor NT5 is cut off, and an output signal of an inverting output terminal XQ is fixed to high level. COPYRIGHT: (C)2007,JPO&INPIT
