Digital Timer Application
A positive pulse on MASTER RESET resets the counters
and latch. The output goes high and remains high until the
number of pulses, selected by A and B, are counted. This
circuit is retriggerable and is as accurate as the input fre-
quency. If additional accuracy is desired, an external clock
can be used on pin 3. A setup time equal to the width of the
one-shot output is required immediately following initial
power up, during which time the output will be high.
