TYPICAL APPLICATIONS
Divide by N Counter (N
≤ 10) with N Decoded Out-
puts.
When the N
th decoded output is reached (Nth
clock pulse) the S-R flip-flop (constructed from
two NOR gates of the HCC/HCF4001B) gener-
ates
a
reset
pulse
which
clears
the
HCC/HCF4017B to its zero count. At this time, if
the N
th decoded output is greater than or equal
to 6, the COUT line goes high to clock the next
HCC/HCF4017B
counter
section.
The
”0”
decoded output also goes high at this time. Coin-
cidence of the clock low and decoded ”0” output
high resets the S-R flip flop to enable the
HCC/HCF4017B.Ifthe N
th decoded output is
less than 6, the COUT line will not go high and,
therefore, cannot be used. In this case ”0”
decoded output may be used to perform the
clocking function for the next counter.
