HD74HC109 Overview
Each flip-flop has independent J, K , preset, clear and clock inputs and Q and Q outputs. This device 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 acplished by a low logic level on the corresponding input.
