There is my situation (I use MS14) -
I have to make counter that produce 1 pulse every time its outputs equal to 127 (0111 1111).
so I have it done.
It works but ,
- take a look at attached pictures
- It creates an extra pulse, but only when it counts down.
I was thinking that is something wrong with 7430 – but I have made other version of 8input NAND – the same result.
Another thought was – there is something wrong with the model of 74193.
But I have made it as real piece of HW. The same thing – there is that damn extra pulse.
What might be a problem? Any opinion is very appreciated..
Thanks a lot Michael
