Datasheets, Manuals or Parts. This was my first experiment with digital logic though, so maybe it will just make more sense as I work with things. Jan 26, 6. We’ll need the schematic you’re useing to help.

I’ve tried many different set-ups but haven’t had any luck. No, datqsheet an datasheft now. You would then have a problem of converting from binary to bcd for use in the display. They all just stay at low, even though I’m giving the counter input a pulse. For a better experience, please enable JavaScript in your browser before proceeding.

I followed your advice and held pin 11 load pin low and datashdet pin 14 reset high and the counter counted! Quote of the day.

So my first project has been to try and make a 7-segment display count up from 0 to 9 using some kind of button press. Jul 17, 22, 1, When I flip the switch I know I’m getting a datashedt pulse maybe that’s the problem, and if so, is there a circuit I can build to make datasjeet quick single pulse?

This IC is a discontinue item. Jan 26, 8. My best guess is that the pulse is too slow, but even when I apply a Hz square wave nothing happens.

I hope I’ve described my situation well enough, I just can not figure out why the counter isn’t datasneet. Jan 26, 4. Right now I have a chip debouncing a switch and and output from that going into the count-up terminal of the The counter chip I had on hand was aand I’ve spend a lot of time reading up on it and trying to make it work, but for the life of me I can’t get the thing to count.
