WebBoth DFF and D-Latches are tiny devices that store bits of data. The biggest difference between the two is how they keep their data. D-LATCH is an electrical device that stores a single piece of data. When the clock input is high, the D latch is used to capture (or 'latch') the logic level on the Data line (Tarnoff, 2007).
