down counter using 74193 ic

Articles Top Articles Search resources. So my first project has been to try and make a datasheey display count up from 0 to 9 using some kind of button press. Apr 14, 7, We’ll need the schematic you’re useing to help.

Jan 28, 9, I hope I’ve described my situation well enough, I just can not figure out why the counter isn’t counting. By continuing to use this site, you are consenting to our use of cookies. Jan 26, 5.

I followed your advice and held pin 11 load pin low and held pin 14 reset high and the counter counted! Any help would be great.

My best guess is that the pulse is too slow, but even when I apply a Hz square wave nothing happens. Jan 26, 8. You May Also Like: No, create an account now. This was my first experiment with digital logic though, so maybe it will just make more sense as I work with things.
