CD4017 4017 A Decade Counter with Decoded Output CMOS logic gates


CD4017 CMOS-Decade counter/divider And also use to build all kinds of the timer, LED sequencers and controllers circuits.
The IC 4017 counts with 5 D-type flip-flops. 
Decoding and control are by 16 inverters and 15 gates.
The CD4017 is a CMOS Decade counter IC. 
CD4017 is used for low range counting applications. 
It can count from 0 to 10 (the decade count). The circuit designed by using this ic will save board space and also time required to design the circuit. 
CD4017 is as ‘Johnson 10 stage decade counter’.
