HD74HC4017 Decade Counter / Divider REJ03D0644-0200 (Previous ADE-205-530) Rev.2.00 Mar 30, 2006 Description The HD74HC4017 is a 5-stage divide-by-10 Johnson counter with ten decoded outputs and a carry-out bit. High-speed operation and spike-free outputs are obtained by use of the Johnson decade counter configuration. The ten decoded outputs are normally low and go high only at their respective decimal time periods. A high signal on Reset R asynchronously clears the decade counter and sets the carry output and Y0 high. With CE low, the count is advanced on a low-to-high transition at C input. Alternatively, if C is high, the count is advanced on a high-to-low transition at CE. Each decoded output remains high for one full clock cycle. The carry output is high while Q0, Q1, Q2, Q3 or Q4 is high, then is low while Q5, Q6, Q7, Q8 or Q9 is high.
