Would it be suitable to run into another decade counter and get valid divide by ten BCD on all Q outputs if I run Qd from one into the clock of another? Forums New posts Search forums.

Oh, Texas Instruments say it is obsolete do 7h4c390 show its datasheet. For a better experience, please enable JavaScript in your browser before proceeding. Did you look at the datasheet of the SN74HC? The TTL counter is such a beast. Using a Qd output as the gate input for a frequency counter would be a bad idea! Someone must have produced a table, but extensive Googling fails to find it!

Space Varmint New Member Sep 1, Q0 would be Qa. And when you want to cascade them, the various stages will be rippled even though within each stage it’s synchronous. Daatasheet instance, the synchronous decade counter is synchronous in its counting only.

You’re maybe confusing this with the term “symmetrical”. Apr 14, 4.

Switching lots of connections simultaneously. But you’ll still potentially have a non-symmetrical Qd output if it’s not a straight binary counter. To participate you need to register.

Parallel load and reset are asynchronous operations.

As mentioned, it takes a pretty special application of a counter such that you require a symmetrical Qd output. You must log in or sign up to reply here.

I know the pin strappings for divide by 4 example 14 to 215 daasheet 32,4,8,12,14 to Ground1 in and 13 out and divide by from a Mr Carlson’s Lab YouTube clip, but I would like to find dayasheet pin strappings for the other possibilities I believe I could divide by 2,5,10,20,25,50? That wasn’t a billed response was it? You must log in or register to reply here. If they’re ripple counters, they’ll ripple in cascade.
