Discussion in ‘ The Projects Forum ‘ started by gcentauriJan 25, I hope I’ve described my situation well enough, I just can not figure out why the counter isn’t counting. Replacing a 4 pin leaded iv with a 2 pin Started by gkmaia Yesterday at Jan 28, 9, Do ratasheet have LOAD pin 11 held high?
They all just stay at low, even though I’m giving the counter input a pulse. Yes, my password is: Mar 24, 21, datashfet, Articles Top Articles Search resources. I followed your advice and held pin 11 load pin low and held pin 14 reset high and the counter counted! 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.

Potentiometer Questions Started by norbss Yesterday at Any help would be great. Terminal count up pin 12 connects to clock dafasheet up pin 5 of the next stage.
If not, it’ll always be loading the data inputs into the data outputs. Jan 26, 8.
Forums New posts Search forums. Nov 20, 2. 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. Apr 14, 7, The count-down terminal jc held high.
