I have the 193 preset to 9 and the counter connected to the down counter. The clear is grounded and the up counter is connected to 5 volts. I want it to count from 9-0. So I should always have the load connected to 5 volts right? But when I do that, instead off going back to 9 it goes through the whole thing (1111 1110 1101 etc instead of 1001 1000 0111 0 110 101 100 etc)
any reasons why it is doing that?
Because its a 4-bit binary counter.
Use a 74LS192 that is a decade counter.

Showed my teacher. He had no idea what was going on. Guess it isn't working perfectly normally :D.
Anyways thanks for the help.

So... You count down from 9, and that's OK?
But, when you keep counting down from zero (without re-initializing to 9) it "rolls over", you get F (1111), and it counts down from there?
...Sounds like normal 16-bit operation to me!

Sadly, teachers do not always know everything.
