Hello First question here. I think I got it now.

Dstasheet instance, the synchronous decade counter is synchronous in its counting only. Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. I intend to use the 74hc data sheet: Apr 14, 2.

Welcome to our site! Is the Qd output the divide by 10 frequency?

So that’s the purpose of the “other” mode. I know the pin strappings for divide by 4 example 14 to 215 to 32,4,8,12,14 to Ground1 in and 13 out and divide by from a Mr Carlson’s Lab YouTube datashdet, but I would like to find the pin strappings for the other possibilities I believe I could divide by 2,5,10,20,25,50?

You’re maybe confusing this with the term “symmetrical”. Click here to register now. Did you derive that from the data sheet?

Oh, Texas Instruments say it is obsolete do not show its datasheet. For a better experience, please enable JavaScript in your browser before proceeding.

And when you want to datxsheet them, the various stages will be rippled even though within each stage it’s synchronous.

The Qd output of most any counter that is not a pure binary counter is often non-symmetrical, that is, the output is not a perfect square wave. I want datashwet experiment with 74HC chip. Someone must have produced a table, but extensive Googling fails to find it! That wasn’t a billed response was it?

Thread starter Space Varmint Start date Sep 1, However, if you don’t use the outputs to drive a display, you can switch the divide-by-2 section with the divide-by-five section so that the divide-by-two section is last in each decade chain and then you WILL have a symmetrical output.
