1 EC262 Topic 12: The T and J-K Flip Flops A flip flop is a clocked device that stores a 0 or a 1. The value stored by a flip flop can only change… Have we seen any exceptions to this rule? What do you mean by “ change the flip flop’s state ”? What is state ? Last week : We saw that the R-S latch can be used to implement the S-R flip flop (also called the R-S flip flop ). This type of flip flop is not used often since: As a result of these deficiencies, the S-R flip flop is not often encountered as a circuit element. So…why did we bother studying it? D flip flops, however, are not perfect as memory devices; there’s a problem with this flip flop that you surely noted in lab: The D type flip flop is very common (perhaps the most commonly encountered flip flop), used all the time everywhere. This week : To address the issue noted above, the J-K flip flop was devised. After examining this flip flop, we will examine one more (the T flip flop), and then talk about the design of circuits that use these devices. The J-K Flip Flop
