In electronics , a flip – flop or latch is a circuit that has two stable states and can be used to store state information. A flip – flop is a bistable multivibrator. The circuit can be made to change state by signals applied to one or more control inputs and will have one or two outputs.
It is the basic storage element in sequential logic. The stored data can be changed by applying varying inputs. The basic formation of flip flop is to store data.
They can be used to keep a record or what value of variable (input, output or intermediate). During my college days (years back), it took me long time to understand the Flip-flop. This the Most important component in Digital Electronics.
Every Electronics Engineer must thoroughly understand this. That is the reason I am explaining this step by step. Why are flip – flops named so?
What is the basic concept of flip flops in electronics ? A simple flip – flop can be defined in terms of two NAND logic gates. Because flip – flops operate on an input .
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.
A combination of number of flip flops will produce some amount of memory. In the parlance of electronics , a flip – flop is a special type of gated latch. The difference between a flip – flop and a gated latch is that in a flip – flop , the inputs aren’t enabled merely by the presence of a HIGH signal on the CLOCK input. Instea the inputs are enabled by the transition of the CLOCK input.
So far, we’ve studied both S-R and D latch circuits with enable inputs. Flip – flop for their memory. The latch responds to the data inputs (S-R or D) only when the enable input is activated. In many digital applications, however, it is desirable to limit the responsiveness of a latch circuit to a very short period of time instead of the entire duration that the . That’s the most easy way to make logic remember something.
D flip – flop is simpler in terms of wiring connection compared to JK flip – flop. The flip flop is a basic building block of sequential logic circuits. It is a circuit that has two stable states and can store one bit of state information. The output changes state by signals applied to one or more control inputs. More of these allow the storage of large amounts of information.
There are many types of flip – flop Electrical circuits such as D- flip flop , Latch, etc.
