Description
The ’HC109 and ’HCT109 are dual J-K flip-flops with set and
reset. The flip-flop changes state with the positive transition
of Clock (1CP and 2CP).
The flip-flop is set and reset by active-low
respectively. A low on both the set and reset inputs
simultaneously will force both Q and
However, both set and reset going high simultaneously
results in an unpredictable output condition.
Q outputs high.
