down counter using 74193 ic

In order to use the ‘, you will have to decode the 10 count and use it to clock the next stage and reset the first stage. You would then have a problem of converting from binary to bcd for use in the display. This was my first experiment with digital logic though, so maybe it will just make more sense as I work with things.

Datasheets, Manuals or Parts. This IC is a discontinue item. My best guess is that the pulse is too slow, but even when I apply a Hz square wave nothing happens.

When I flip datashset switch I know I’m getting a slow pulse maybe that’s the problem, and if so, is there a circuit I can build to make a quick single pulse? Jan 26, 7.

I hope I’ve described my situation well enough, I just can not figure out why the counter isn’t counting. Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets.

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. Thread starter lhanx2 Start date Dec 16, Nov 20, 2. The count-down terminal is held high. If not, it’ll always be loading the data inputs into the data outputs. I’d would not go with the because it counts in binary. Click here to register now.
