Please see post #11 above. If I read the OP correctly, he wanted a simple set/reset type flip-flop which this circuit provides. It may be simpler to use a octal latch i.e. 74273 types, but they don't have individual sets/resets.
The 74 series has higher current variants (AC), but they are limited to 5V supplies (I think the OP was looking for 9/12V capability). The 4049 or 4069 is a hex inverter, but w/o schmitt trigger inputs. AFAIK, the 40106 is the only version that meets his requirements.
