Dual J-k Flip-flop With Set And Reset Positive-edge Trigger
The ?HC109 and ?HCT109 are dual J-K ?ip-?ops with set and reset. The ?ip-?op changes state with the positive transition of Clock (1CP and 2CP). The ?ip-?op is set and reset by active-low S and R, respectively. A low on both the set and reset inputs simultaneously will force both Q and Q outputs high. However, both set and reset going high simultaneously results in an unpredictable output condition.
