Description

Each HD74HC109  flip-flop has independent J, K, preset, clear and clock inputs and Q and Q outputs. This HD74HC109 is edge sensitive to the clock input and changes state on the positive going transition of the clock pulse. Clear and preset are independent of the clock and accomplished by a low logic level on the corresponding input.
