CD4017BC • CD4022BC  
Decade Counter/Divider with 10 Decoded Outputs •  
Divide-by-8 Counter/Divider with 8 Decoded Outputs  
General Description  
The CD4017BC is a 5-stage divide-by-10 Johnson counter  
Features  
Wide supply voltage range: 3.0V to 15V  
with 10 decoded outputs and a carry out bit.  
High noise immunity: 0.45 VDD (typ.)  
The CD4022BC is a 4-stage divide-by-8 Johnson counter  
with 8 decoded outputs and a carry-out bit.  
Low power Fan out of 2 driving 74L  
TTL compatibility: or 1 driving 74LS  
Medium speed operation: 5.0 MHz (typ.)  
with 10V VDD  
These counters are cleared to their zero count by a logical  
“1” on their reset line. These counters are advanced on the  
positive edge of the clock signal when the clock enable sig-  
nal is in the logical “0” state.  
Low power: 10 µW (typ.)  
Fully static operation  
The configuration of the CD4017BC and CD4022BC per-  
mits medium speed operation and assures a hazard free  
counting sequence. The 10/8 decoded outputs are nor-  
mally in the logical “0” state and go to the logical “1” state  
only at their respective time slot. Each decoded output  
remains high for 1 full clock cycle. The carry-out signal  
completes a full cycle for every 10/8 clock input cycles and  
is used as a ripple carry signal to any succeeding stages.
