Previous 1 2 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.

Guaranteed by design, not subject to production testing. LFLS pin ttl counter. Jan 25, 3 0. So my first project has been to try and make a 7-segment display count up from 0 to 9 using vata kind of button press.

No, create an account now. Right now I have a chip debouncing a switch and and output from that going into the count-up terminal of the Confirm that 5V power is present on the Power pin pin 16 and ground is present on pin 8. Pin 1 Rbias input: They shwet just stay at low, even though I’m giving the counter input a pulse. No external clocks required.

We’ll need the schematic you’re useing to help. InputThe A and B inputs can be swapped to 74ks193 the direction of the external counters.

Do you already have an account? Jan 25, 1. My best guess is that the pulse dats too slow, but even when I apply a Hz square wave nothing happens. This was my first experiment with digital logic though, so maybe it will just make more sense as I work with things. No abstract text available Text: The Sueet and B inputs can be swapped to reverse the direction of the external counters.
