can any one state the working of decade counter when ip is given from ic555 and also why is there outputs only at select terminals of the counter for different selections is there any set of rules governing it

if so do post them
 

Hi,

If using something like a 4017 decade counter then the internal logic they used to create the chip governs how it preforms.

If you want to understand more of the detailed workings of a decade counter then perhaps start looking here.

Hi,

When Clr is pulled low it resets all the f/fs to 0, when running normally / counting and clr is held high and each f/f will count up in sequence.

Have a look at this tutorial, you can use a 555 instead of the 4093 they use for the signal generator.
