That doesn't work well on analog designs. Often you must filter the supply of one 74HC14 because it is used as a low noise oscillator, but not on all the others. Or a design I just had where more than a dozen opamps of same type all had to have their own personal supply. > I'll try and hack up a nicer example than just the static flipflop I > already have.
