HEF4017B
5-stage Johnson decade counter
13. 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).
