twice the delay of the gate and the feedback element.

0 The flip–flop changes state only when all “1’s” or all “0’s” are

Qn entered. This configuration may be extended by cascading M5

Qn gates to cover n–inputs where all inputs must be “1’s” or “0’s”

Qn before the output will change. As an example, this configura-

Qn tion is useful for controlling an n–stage up/down counter that is

Qn without flipping over (from all “1’s” to all “0’s”.)
