Hi, I am looking to build some very simple state machines, with JK flip flops. I am planning to run them off a 9 volt battery, if that is feasible. Does anyone have a suggestion on what JK flip flop to buy, preferably from Mouser? I know Mouser has about 300 different parameters to pick from, I just want someone to suggest a good starting JK. I am not going to be doing anything high power, or fast frequency switching. I believe I am going to want a positive trigger though. Anyone have a good suggestion?
