ANedge triggeredSR flip-flop with extra logic such that oNly oNe of the R aNd S iNputs is eNabled at aNy time. This preveNts a race coNditioN which caN occur wheN both iNputs of aN RS flip-flop are active at the same time. IN a JK flip-flop the R aNd S iNputs are reNamed J aNd K. The set iNput (J) is oNly eNabled wheN the flip-flop is reset aNd K wheN it is set. If both J aNd K iNputs are held active theN the outputs will chaNge ("togle") oN each falliNg edge of the clock. JK flip-flops caN be used to build a biNary couNter with a reset iNput. . [Was it Named after Jack Kilby?] (2004-07-17)
