PURPOSE:To obtain a timer which delivers no timer output with a conditional signal that is supplied with a delay, by driving a monostable multivibrator which produces a timing pulse with the output of the timer. CONSTITUTION:A timing pulse is applied to a timer unit 30 via an FF10. A monostable multivibrator 50 is driven by a unit 30. A conditional signal is supplied to an AND circuit 40 via an FF20. If the FF2 is not set by the conditional signal before the vibrator 50 is driven, no output 51 is produced at the circuit 40. |
