SR(set-reset) flip flop






The logic gate for flip-flop







The logic gate in SET mode. (double click the image to see how the logic works)








The logic gate in RESET mode ( double click the image to see how the logic works)




An SR(set-reset) Flip Flop is an arrangements of logic gates that maintains a stable output even after the inputs are turned off. This simple flip flop circuit has a set input (S) and a reset input (R). The set input causes the output of 0 (top output) and 1 (bottom output). The reset input causes the opposite to happen (top = 1, bottom =0). Once the outputs are established, the wiring of the circuit is maintained until S or R go high, or power is turned of to the circuit.
