PURPOSE:To save number of monostable multivibrators by constituting the titled clock interruption detecting circuit by the combination of a flip-flop with high circuit integration receiving plural clocks and monostable multivibrators. CONSTITUTION:For example, a clock 1 is given to a data terminal D of a D flip-flop circuit 11 receiving two clocks 1, 2, the clock 2 is given to a clock terminal CK, the clock 2 allows the clock 1 to be held by the D flip-flop circuit (D-F.F circuit) 11 and the interruption of clocks 1, 2 is detected depending whether or not the holding repetitive time is within a time constant of a monostable multivibrator section 12. Thus, number of monostable multivibrators is less and the clock interruption detecting circuit 10 is formed with simpler constitution. |
