Trouble loading data in a 4029 Up/Down counter
(lemmy.world)
I have to design a programmable frequency/clock divider circuit using the 4029 IC. Theoretically, the circuit should start to count down backwards from a given number and when it reaches 0, the 4029 should load the data from the ABCD pins.
The issue is that the countdown stops at 0 and PE doesn't get back to the LOW state. It loads the number, but the SR latch never changes its state so the IC can start counting again. I tried everything and nothing fixes the issue. What can be done in this case? Thanks 🍻
Seems like that was the issue. Thanks a lot for the help 🍻 :) I replaced the SR latch with a D Flip Flop and everything works perfect.
