Just saying hello Started by MichaelaJoy Yesterday at 6: Did you derive that from the data sheet? But if the OP is only interested in clocking a subsequent stage, symmetrical output isn’t required. Did you look at the datasheet of the SN74HC? Hey, but thanks for datashewt.

Thanks for that description. I don’t know what that other configuration is. By continuing to use this site, you are consenting to our use of cookies. Apr 14, 4. But you’ll still potentially have a non-symmetrical Qd output if it’s not a straight binary counter.

If I remember correctly it is an asynchronous 74yc390.

Thread starter Space Varmint Start date Sep 1, Would it be suitable to run into another decade counter and get valid divide by ten BCD on all Q outputs datsheet I run Qd from one into the clock of another? Forums New posts Search forums. Apr 14, 2. The TTL counter is such a beast. Hello First question here. Switching lots of connections simultaneously.

That wasn’t a billed response was it?

Apr 14, 9. 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. I want to experiment with 74HC chip.

After that, you can post your question and our members will help you out. If they’re ripple counters, they’ll ripple in cascade. Apr 14, 7. And just because a counter is a synchronous counter doesn’t mean that it’s synchronous in every sense or will be synchronous in cascade.

I noticed your signature. You’re maybe confusing this with the term “symmetrical”.
