HD74HC78 Dual J-K Flip-Flops

This flip-flop is edge sensitive to the clock input and change state on the negative transition of the clock pulse. Each flip-flop has independent J, K, and preset inputs and Q and Q outputs. Two flip-flops are controlled by a common clear and a common clock. Preset and clear are independent of the .
