What is SR Flip Flop?

It is a Flip Flop with two inputs, one is S and the other is R. S here stands for Set and R here stands for Reset. Set basically indicates set the flip flop which means output 1 and reset indicates resetting the flip flop which means output 0. Here, a clock pulse is supplied to operate this flip-flop, hence it is a clocked flip-flop....

Construction of SR Flip Flop

We can construct SR flip flop with two ways, one is with 2 NOR Gates + 2 AND Gates and other is with 4 NAND Gates....

Basic Block Diagram of SR Flip Flop

The basic block diagram contains S and R inputs, and between them is clock pulse, Q and Q’ is the complemented outputs....

Working of SR Flip Flop

Case 1: Let’s say, S=0 and R=0, then output of both AND gates will be 0 and the value of Q and Q’ will be same as their previous value, i.e, Hold state. Case 2: Let’s say, S=0 and R=1, then output of both AND gates will be 1 and 0, correspondingly the value of Q will be 0 as one of input is 1 and it is a NOR gate so it will ultimately gives 0, hence Q gets 0 value, similarly Q’ will be 1. Case 3: Let’s say, S=1 and R=0, then output of both AND gates will be 0 and 1, correspondingly the value of Q’ will be 0 as one of input to NOR gate is 1, so output will be 0 ultimately and this 0 value will go as input to upper NOR gate, and hence Q will become 1. Case 4: Let’s say, S=1 and R=1, then output of both AND gates will be 1 and 1 which is invalid, as the outputs should be complement of each other....
