Types Of Flip Flops
Let us study the different types of flip-flops
D Flip Flop
These are basic flip-flops used in appliances like counters. There are two inputs to the D flip flop, one is D and the other is D’. Corresponding to this input, an output is generated which changes with the clock pulse. Let us understand this using a truth table.

SR Flip Flop
SR flip flop is most common because it is very simple to design and easier to understand. It consists of two inputs namely ‘Set’ and ‘Reset’ pin and it has corresponding output pins Q and Q’. When the input of ‘S’ pin is high, the output ‘ is high and Q’ is low. Let us understand this with the truth table of this flip flop.

JK Flip Flop
JK flip flop is made by adding some advancements in SR flip flop. It is made specially to design the case where J=1 and K=1. In case, when the inputs applied to the flip flop are different, the output is the value of input J and when the inputs are same ( when J and K are both high) then the output toggles from one state to another. Let us understand this from the truth table.

T Flip Flop
T flip flops are similar to JK flip flop except that they have one input instead of two. In this, J and K are connected together and the output changes accordingly as the clock pulse is provided as an input. Let us understand this from the truth table.

Applications of Flip Flop
Digital electronics is a very important branch of engineering used for circuit design and data storage. Flip Flops are an important part of digital electronics and are widely used for different purposes. In this article, we will study what are flip flops and the principles used in the working of flip flops. We will also see the applications of flip-flops through certain examples. Later we will discuss the advantages and disadvantages of flip-flops. The article will conclude with a discussion about the future trends of flip flops.
