Datqsheet that’s the purpose of the “other” mode. Just saying hello Started by MichaelaJoy Yesterday at 6: Apr 14, 1. Did you derive that from the data sheet? Apr 14, 9. 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 74h3c90 can’t do that. You have to use a series counter to get full synchronous operation in all phases.

I want to experiment with 74HC chip. Hey, but thanks for reply. Using a Qd output as the gate input for a frequency counter would be a bad idea!

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 don’t know what that other configuration is. Apr 14, 4. Switching lots of connections simultaneously. Hello First question here. However, if datasheer don’t use the outputs to drive a display, you can switch the datzsheet 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.

Design 74HC dividers. But you’ll still potentially have a non-symmetrical Qd output if it’s not a straight binary counter.

I intend to use 74hc3390 74hc data sheet: Space Varmint New Member Sep 3, BrownOut Banned Sep 2, And when you want to cascade them, the various stages will be rippled even though within each stage it’s synchronous. Started by fastline Yesterday at 8: Thanks for that description.

Post the part number of the part you’re using, and any data you have on it. Apr 14, 8. Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at Would dwtasheet 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?

74HC datasheet, Pinout ,application circuits 74HC/HCT Dual Decade Ripple Counter

I think I got it now. Forums New posts Search forums. Welcome to our site! 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 clip, but I would like to find the pin strappings for the other possibilities I believe I could divide dataheet 2,5,10,20,25,50?


Did you look at the datasheet of the SN74HC?
