Flip-flops and latches can be divided into common types: the SR ("set-reset"), D ("data" or "delay" ), T ("toggle"), and JK. The behavior of a particular type can be described by what is termed the characteristic equation, which derives the "next" (i.e., after the next clock pulse) output, Qnext in terms of the input signal(s) and/or the current output, . list of all the stores
