Hi Guys A couple of questions about this non-volatile flip-flop posted by a member here a couple of years ago perhaps. I have tested this, and without the cores, it’s still an ordinary volatile flip-flop. Why are the pair of 2N3638A even there? I understand they will just pull the base of either 2N3904 low, and being capacitor coupled, the 2N3638A inputs will only act on pulses. So what? Why wouldn’t you just pull down the 2N3904 bases directly? Even if it has to be done through capacitors to prevent the 2N3904 staying on, and blowing up. Secondly, It there an obvious way to add a clock input to this? Cheers, Brek.
