Certain timing parameters would be listed in the specification sheet of a flip-flop. Some of these
parameters, as we will see in the paragraphs to follow, are specific to the logic family to which the
flip-flop belongs. There are some parameters that have different values for different flip-flops belonging to the same broad logic family. It is therefore important that one considers these timing parameters before using a certain flip-flop in a given application. Some of the important ones are set-up and hold times, propagation delay, clock pulse HIGH and LOW times, asynchronous input active pulse width, clock transition time and maximum clock frequency
