Space Varmint New Member Sep 3, However, if you don’t datashset 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. Did you derive that from the data sheet? Thread starter Space Varmint Start date Sep 1, Datasheeet a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at I want to experiment with 74HC chip.

I know the pin strappings for divide by 4 example 14 to 215 to 32,4,8,12,14 to Ground1 in and dataxheet out and divide by from a 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? Using a Qd output as the gate input for a frequency counter would be a bad idea! Mikebits Well-Known Member Sep 1, 7hc390 Similar Threads Parallel Pin Connections. After that, you can post your question and our members will help you out.
It was not a stupid question. Switching lots of connections simultaneously. You’ll need to choose a username for the site, which only take a couple of moments here.
You’re maybe confusing this with the term “symmetrical”. Click here to register now. Apr 14, 3. BrownOut Banned Sep 1, Post the part number of the part you’re using, and any data you have on it.
So that’s the purpose of the datsheet mode. But you’ll still potentially have a non-symmetrical Qd output if it’s not a straight binary counter. You must datsheet in or register to reply here. Apr 14, 1. Apr 14, 5. You must log in or sign up to reply here. Design b 74HC divoders.
I think I got it now. 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?

It appears, from looking at the datasheet, that indeed Q4 is a divide by 10 output, when the chip is configured for a decade counter.
If they’re ripple counters, they’ll ripple in cascade. That wasn’t a billed response was it?
