I'm building quite a complex circuit, and it has three 74HC595 (serial to parallel). Well, I managed to make them work fine, after lots of problems (I had to add pull resistors in clock inputs, etc..) but when I add decoupling capacitors (between VCC IC pin and groung) it starts to get wrong outputs.
I use 0,1 uF ceramic capacitors for the task.
Isn0t it suppose to wirk better with decoupling capacitors?? It works great for me without them, and bad with them... why?...
