Dual J-K Flip-Flop with Set and Reset
Positive-Edge Trigger
Description
The 鈥橦C109 and 鈥橦CT109 are dual J-K 鏗俰p-鏗俹ps with set and
reset. The 鏗俰p-鏗俹p changes state with the positive transition
of Clock (1CP and 2CP).
The 鏗俰p-鏗俹p 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.
