产品概述
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 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.
