flip flop sr 1 flip flop jk 2 latch nand 3 flip flop tipo d 4 The logic symbol of an SR Flip-Flop is shown below: SR Flip-Flop using NAND Gates (Technically, RS Flip-Flop) An SR flip flop can also be designed by cross coupling of two NAND gates, but the Hold and Forbidden states are reversed. It is an active low input SR flip – flop and hence let us call it RS Flip-Flop. The circuit of SR flip – flop. 5 Consider a SR flip flop using NAND gates: The truth table can be given as: Now, consider SR flip flop using NOR gates: The truth table can be given as: The circuit will work in a similar way to the NAND gate circuit above, except that the inputs are active HIGH and the invalid condition exists when both its inputs are at logic level “1”. 6 digital logic 7 Flip Flop Types and Their Truth Tables 8 Toggle share options 9 RS Flip 10
