Dual J-K Flip-Flops (with Preset)
Description
This flip-flop is edge sensitive to the clock input and change state on the negative going transition of the
clock pulse. Each one has independent J, K, clock, and preset inputs and Q and
Q inputs. Preset is
independent of the clock and accomplished by a low level on the input.
