CMOS 4026 decade counter and 7-segment display driver

[sundayuneedlove]

Is there a way to use this chip as an alternative to 4017? I don't want to drive LED's instead I want to make an audio sequencer with each ouput applying voltage to a different resitor and back to 555 etc..(plenty more videos on this) but I can not find 4017 where I live, although 4026 is VERY easy to find....I do however like the thought of also running the clock display while my sequencer runs for added touch....

so this will count ''automatically'' with a clock input, i don't need a darlington, and a 4017, and loads of shit? sweetness

@amando96

nope. that's it. all you need

[amando96]

@davidbball13 cool, is it made for common cathode, or anode displays?

nice work

hey, were did you get the 4026? I can't find one!

You'll have to mail-order, unfortunately Radio Shack doesn't have all the 'goodies' like they used to :P

cool

I think the digit 6 should have no segment A, and I think the digit 9 should have no segment D.

[davidbball13]

Many people believe that. This is how the IC is designed

[Richaarddd]

How come it doesn't suffer from the flicker that is common in the 4026 setup? Or is the camera not able to pick it up?

[davidbball13]

I have never heard of flicker from a 4026. Even in person I have never noticed it. No matter what the frequency I have them running at I have not seen any flickering

[IamTheTimmy]

@Richaarddd to the best of my understanding, the flickering comes from multiplexing multiple 7 segment LED displays together. it looks like he's using one IC per display instead of multiplexing, so no issue of flickering should be had.

--now I've noticed on my 4026 experiments, that the IC makes the display "blink" when changing numbers.

replying a year later, I hope it is still relevant, or at least accurate. had more to say, but out of space here.

@davidbball13

nice breadboard work!

[AdirHaker]

you have schem?

[davidbball13]

No I don't, All I did was follow the data sheet and use the divide 10 pin on the chip
