Web3. The asynchronous reset can lead to metastability issues. To understand the metastability issue consider that the clock rising edge comes right after the reset edge. The D flip Flop must have certain minimum time between reset edge and clock edge, called reset recovery time. If this time duration is violated, the output is not guaranteed.

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, .
