1. General description
The HEF4017B is a 5-stage Johnson decade counter with ten spike-free decoded active
HIGH outputs (Q0 to Q9), an active LOW carry output from the most significant flip-flop
(Q5-9), active HIGH and active LOW clock inputs (CP0, CP1) and an overriding
asynchronous master reset input (MR).
The counter is advanced by either a LOW -t o-HIGH t ransiti on at CP0 wh ile CP1 is LOW or
a HIGH-to-LOW transition at CP1 while CP0 is HIGH (see Table 3).
When cascading counters, the Q5-9 output, which is LOW while the counter is in states 5,
6, 7, 8, and 9, can be used to drive the CP0 input of the next co unter. A HIGH on MR
resets the counter to zero (Q0 = Q 5-9 = HIGH; Q1 to Q9 = LOW) independent of the clock
inputs (CP0, CP1).
Automatic counter code correction is provided by an internal circuit: following any illegal
code the counter returns to a proper counting mode within 11 clock pulses.
Schmitt trigger action makes the clock inputs highly tolerant of slower rise and fall times.
It operates over a recommended VDD power supply range of 3 V to 15 V referenced to V SS
(usually ground). Unused inputs must be connected to VDD, VSS, or another input.

12. Application information
Some examples of applications for the HEF4017B are:
•Decade counter with decimal decoding
•1 out of n decoding counter (when cascaded)
•Sequential controller
•Timer
Figure 11 shows a technique for extending the number of decoded output states for the
HEF4017B. Decoded outputs are sequential within each stage and from stage to stage,
with no dead time (except propagation delay).
Enabling the counter on CP1 when CP0 is HIGH, or on CP0 when CP1 is LOW, causes an extra count.
