That wasn’t a billed datashret was it? As mentioned, it takes a pretty special application of a counter such that you require a symmetrical Qd output. Thanks for that description. Potentiometer Questions Started by norbss Yesterday at And when you want to cascade them, the various stages will be rippled even though within each stage it’s synchronous.

Apr 14, 9. Oh, Texas Instruments say it is obsolete do not show its datasheet. Apr 14, daasheet. Hey, but thanks for reply. But you’ll still potentially have a non-symmetrical Qd output if it’s not a straight binary counter.
I want to experiment with 74HC chip. I think I got it now.
Datasehet Varmint New Member Sep 3, Mikebits Well-Known Member Sep 1, I intend to use the 74hc data sheet: You’ll need to choose a username for the site, which only take a couple of moments here. 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 datssheet Mr Carlson’s Lab YouTube clip, 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?
Is the Qd output the divide by 10 frequency? Apr 14, 4. Q0 would be Qa. Using a Qd output as the gate input for a frequency counter would be a bad idea! Design 74HC dividers. Apr 14, 1. So that’s the purpose of the “other” mode. If I remember correctly it is an asynchronous signal.

Design b 74HC divoders. Media New media New comments Search media. The TTL counter is such a beast. But if the OP is only interested in clocking a subsequent stage, symmetrical output isn’t required.
Forums New posts Search forums. Switching lots of connections simultaneously. 74c390 Varmint New Member Sep 1, Parallel load and reset are asynchronous operations. I noticed your signature. You do have to be careful with counters.

After that, you can post your question and our members will help you out. If they’re ripple counters, they’ll ripple in cascade. But the larger counter chips that incorporate several like stages do not have access to the divide-by-two stages so you can’t do that. Apr 14, 3. It was not a stupid question. Apr 14, 5.
