Latches in Digital Logic
Latch is a digital circuit which converts its output according to its inputs instantly. To implement latches, we use different logic gates. In this article, we will see the definition of latches, latch types like SR, gated SR, D, gated D, JK and T with its truth table and diagrams and advantages and disadvantages of latch.
