    A latch is another name for a flip flop, or a set reset multivibrator. It is used to store binary numbers.

    or it could be a relay. The word 'latch' means it's an assembly or component that exhibits a memory state, functioning as a 1 bit memory cell.
    More context would be needed to show how a specific circuit or component provides a latching function.

    Hello,

    On this page there are links to several types of latches : http://www.play-hookey.com/digital/

    This page comes from the EDUCYPEDia page : http://www.educypedia.be/electronics/digital.htm

    On this page there are more digital electronics pages :

    Among logic designers, a latch is a flip-flop whose output follows the input while the clock is at the active level. When clock goes inactive, the output holds the state it was in at that time.
    This contrasts to a D flip-flop, which is edge-triggered, i.e., the input state that is present when the active clock edge occurs gets transferred to the output. The output will remain in that state until the next active clock edge.
