Typical Applications Characteristics (cont.)
Missing Pulse Detector
The circuit shown in Figure 7 can be used to detect a missing pulse or abnormally long spacing between consecutive pulses
in a train of pulses. The timing interval of the monostable circuit is retriggered continuously by the input pulse train as long as
the pulse spacing is less than the timing interval. A longer pulse spacing, missing pulse, or terminated pulse train permits the
timing interval to be completed, thereby generating an output pulse as shown in Figure 8.

Frequency Divider
By adjusting the length of the timing cycle, the basic circuit of Figure 1 can be made to operate as a frequency divider. Figure
9 shows a divide-by-three circuit that makes use of the fact that retriggering cannot occur during the timing cycle.
