JK flip-flop comes up with an internal SR latch circuit, but it also has a clock installed. To solve this problem a JK flip flop is used. The other problem is the correct latching problem may not occur when the enable pin is high. In SR latch the S = R = 0 should be avoided by the system. A single flip-flop represents two-state, in which data is stored is represented by 1 and the other is represented by 0. Before starting with 74LS73 DUAL JK FLIP-FLOP, let’s first understand that what is it? Flip-Flops and latches are those small devices used to store a single bit.
