The 74F109 is a dual positive edge-triggered JK-type flip-flop featuring individual J, K, clock, set, and reset inputs; also true and complementary outputs. Set (SD) and reset (RD) are asynchronous active low inputs and operate independently of the clock (CP) input. The J and K are edge-triggered inputs which control the state changes of the 74F109 flip-flops as described in the function table. Clock triggering occurs at a voltage level and is not directly related to the transition time of the positive-going pulse. The J andK inputs must be stable just one setup time prior to the low-to-high transition of the clock for predictable operation. The JK design of 74F109 allows operation as a D flip-flop by tying J and K inputs together. Although the clock input is level sensitive, the positive transition of the clock pulse between the 0.8V and 2.0V levels should be equal to or less than the clock to output delay time for reliable operation.
