The T Flip-Flop

The T or "toggle" flip-flop changes its output on each clock edge, giving an output which is half the frequency of the signal to the T input.

It is useful for constructing binary counters, frequency dividers, and general binary addition devices. It can be made from a J-K flip-flop by tying both of its inputs high.
