RS flip-flop Using NAND gates
The RS flip-flop can be constructed using 4 two input NAND gate which is shown in the above figure.
RS Flip Flop
The RS flip-flop is used to store binary information (i.e. 0 or 1). It consists of two inputs, SET and RESET. In RS flip-flop ‘R’ Stands for RESET and ‘S’ stands for SET. The flip-flop keeps its present state even when one or both inputs are deactivated. The flip-flop enters the ‘0’ state when the RESET input is activated, and the ‘1’ state when the SET input is activated.
