描述 Description

This flip-flop is edge sensitive to the clock input and changestate 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 ofthe clock and accomplished by a low logic level on the corresponding input.
