    Flip flop
In summary, a latch is a type of flip-flop that stores data on one of the levels of a clock signal, while a flip-flop stores data on one of the edges of the clock signal. Flip-flops are a subset of gated latches, which are a subset of the basic latch. A 74LS series gated latch chip can be used to make a flip-flop, and a gated SR latch can be used to make an SR flip-flop by creating a custom pulse transition detector circuit to convert a level change into a short spike.

Is latch a type of flip-flop? I'm confuse.

basically a latch stores data on one of the levels of a clock signal (when the signal is either 1 or 0), while the flip-flop stores data on one of the edges of the clock signal (either falling edge or rising edge).

try this

FF is a type of Latch

Using a Latch, you can make a Gated Latch.

Using a Gated Latch, you can make a Flip Flop.

So, FFs are a subset of Gated Latches, which are subsets of the basic Latch (two transistors).


Have you tried using a 74LS series Gated latch chip (don't remember exact part number) to make a Flip Flop? Try it!

Use a gated SR Latch to make an SR Flip Flop.. how? Before the Gate input... make your own custome Pulse Transition Detector.

So your PTD circuitry has to convert a level change into a short spike. You figure a circuit out! (There are a bilion ways to do this)
 

1. Is a latch the same as a flip-flop?

No, a latch is not the same as a flip-flop. While both are sequential logic circuits used to store and manipulate data, they operate differently and have different applications.

2. What is the difference between a latch and a flip-flop?

The main difference between a latch and a flip-flop is in their mode of operation. A latch is level-sensitive, meaning it changes its outputs as long as its inputs remain in a particular state. A flip-flop, on the other hand, is edge-triggered, meaning it only changes its outputs on a clock signal.

3. Are latches and flip-flops interchangeable?

No, latches and flip-flops are not interchangeable. They have different functionalities and cannot be substituted for one another without affecting the overall circuit's performance.

4. What are the main types of flip-flops?

The main types of flip-flops are D flip-flop, JK flip-flop, T flip-flop, and SR flip-flop. Each type has a different triggering mechanism and is used for different applications.

5. Can latches and flip-flops be combined in a circuit?

Yes, latches and flip-flops can be combined in a circuit to create more complex sequential logic circuits. This allows for the storage and manipulation of larger amounts of data and enables the creation of more advanced digital systems.
