D flip flop can be built using NAND gate or with NOR gate. Due to its versatility they are available as IC packages. The major applications of D flip flop are to introduce delay in timing circuit, as a buffer, sampling data at specific intervals. D flip flop is simpler in terms of wiring connection compared to JK flip flop.

After knowing the basics about flip flops, you must be wondering how to construct one! Read here to know about the construction of a basic flip flop circuit using NAND and NOR gate. Also understand their operation and construction with the help of logic diagram

What is Flip Flop? Digital flip flops are memory devices used for storing binary data in sequential logic circuits.Latches are level sensitive and Flip flops are edge sensitive. It means that the latch’s output change with a change in input levels and the flip flop’s output only change when there is an edge of controlling signal.That control signal is known as a clock signal Q.

JK Flip Flop The JK Flip Flop is the most widely used flip flop. It is considered to be a universal flip flop circuit. The sequential operation of the JK Flip Flop is same as for the RS flip flop with the same SET and RESET input. The difference is that the JK Flip Flop does not the invalid input states of the RS Latch (when S and R are both 1).The JK Flip Flop name has been kept on the ...

JK Flip Flop Circuit Diagram. The JK flip flop is probably the most widely used and is considered the universal flip flop because it can be used in many ways. In our previous article we discussed about the S R Flip Flop. Actually, a J K Flip flop is a modified version of an S R flip flop with no “invalid” output state .

The operation of this circuit is quite easy to understand if you draw a pulse diagram for it and analyze the flip flop’s output over time. When the encoder disk spins clockwise, the Q output goes high; when counterclockwise, the Q goes low.

This circuit is an example of a set reset flip flop. Set reset flip flop is the simplest flip flop. This circuit using discrete components. Here is the schematic diagram : When this circuit obtain the power, only one of the transistors will conduct that causing the other components to remain off.

In the next tutorial about Sequential Logic Circuits, we will look at another type of simple edge triggered flip flop which is very similar to the RS flip flop called a JK Flip flop named after its inventor, Jack Kilby. The JK flip flop is the most widely used of all the flip flop designs as it is considered to be a universal device.
