A latch for detecting a state transition of an input signal and generating a self-clearing reset signal on an output. The latch comprises: 1) a transfer gate for passing the input signal to a first node when the input transfer gate is enabled; 2) a transition detector for detecting a transition of the first node from a first to a second state, wherein the transition detector, in response to the transition, disables the transfer gate and enables the reset signal; and 3) a feedback loop circuit for detecting enabling of the reset signal. The feedback loop circuit, in response to the enabling, changes the first node from the second state back to the first state. The transition detector, in response to the changing of the first node back to the first state, disables the reset signal.
