Latch vs Flip-Flop Explained | Difference Between Latch and Flip Flop in Digital Electronics

[00:00:01]Yes, uh So, today we will see uh the difference between flip-flop and latch.

[00:00:07]All right. So, the question may be like in examination, compare flip-flop and latch.

[00:00:13]Okay. So, detailing of flip-flop, types of flip-flop, and everything I have explained in the video, but this is a safe what for example, okay?

[00:00:22]So, what is flip-flop? Flip-flop is what? The bistable device. It is having a two state, right?

[00:00:27]Zero and one, right?

[00:00:29]And latch is also a bistable device whose states are un- also represented as zero and one, right?

[00:00:38]Now, flip-flop may kya hota hai? It checks the input, but the change the output only at time defined by the clock signal. Okay, flip-flop ka output kab kab change hota hai? It depends on the clock signal. Kab chalu hota hai, right?

[00:00:55]And latch mein aisa nahi hota hai. It checks the input continuously and responds to change in the inputs immediately, right?

[00:01:03]Now, the flip-flops are the edge triggered device, and the latch are the level triggered device, right?

[00:01:10]Now, the flip-flops are the gate like not, nor, and and nands are building building blocks of the flip-flop.

[00:01:16]Flip-flop agar banana hai toh gate se bana bana sakte ho. And the latches are also can be made with the with the help of gates, right?

[00:01:26]Now, they're classified into the asynchronous and synchronous flip-flop, right?

[00:01:33]Synchronous and asynchronous flip-flop, but there is no such a classification in the latches, okay?

[00:01:39]Flip-flop always have a clock signal, okay? And latch doesn't have a clock signal, right? The flip-flop can be made from the latches. This is important. The flip-flop can be made from the latches, and latches can be made from the gates, right?

[00:01:55]And example of the flip-flop are SR flip-flop, T flip-flop, D flip-flop, JK flip-flop, and latches. Okay?

[00:02:01]Examples are the SR latch and D latch.

[00:02:04]So, any six points you can write in the examination if the question is of the difference or compare between the flip-flop and latches. Right?
