JK flip-flop

JK flip-flop

   <hardware> An {edge triggered} {SR 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.
