4017

[hamm]

hi i want to use two 4017 in cascade such that first 4017 ic count up to ten then second 4017 ic will be enabled and first one would be disabled when second 4017 ic complete its count then first 4017 ic will be eabled again and so on
can any one help

The only problem with a 4017 is this:
One of the outputs must be HIGH.
It depends on what you actually want to do.
You need to be more specific.
Do you want a "run of 20?"

Bill Bowden uses "Mickey Mouse" AND gates made from diodes:

yep i want a run of 20 continously

The most you can get from two 4017's is a "run of 18" as shown in the previous circuit.

... but you can cascade as many of them as you want to get the desired number of outputs ...
