HCF4017B
TYPICAL APPLICATIONS
DIVIDE BY N COUNTER(N < 10) WITH
DECODED OUTPUTS
TEST CIRCUIT
When the Nth decoded output is reached (Nth
clock pulse) the S-R flip-flop (constructed from two
NOR gates of the HCF4001B) generates a reset
pulse which clears the HCF4017B to its zero
count. At this time, if the Nth decoded output is
greater than or equal to 6, the COUT line goes high
to clock the next HCF4017B counter section. The
"0" decoded output also goes high at this time.
Coincidence of the clock low and decoded "0"
output high resets the S-R flip-flop to enable the
HCF4017B. If the Nth 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.
CL = 50pF or equivalent (includes jig and probe capacitance)
RL = 200K
RT = ZOUT of pulse generator (typically 50)
6/11
