Note: × is the don’t care condition. Characteristics table for SR Nand flip - flop Characteristics table is determined by the truth table of any circuit, it basically takes Q n, S and R as its inputs and Q n+1 as output. Q n+1 represents the next state while Q n represents the present state. While dealing with the characteristics table, the clock is high for all cases i.e CLK=1. The characteristics table for the SR flip flop is given below. A SIMPLE explanation of an SR Flip Flop (or SR Latch). Learn what an SR Flip Flop is, see the SR Flip Flop Truth Table, and a diagram of an SR Flip Flop circuit. Learn what an SR flip flop is, how it works, and how to use it in digital electronics. Find out the truth table, excitation table, and master-slave configuration of SR flip flops. What is Set-Reset (SR) Flip - flop ? Flip flops are an application of logic gates. A flip - flop circuit can stay in a binary state continually (as long as power is transferred to the circuit) before conducted by an input signal to switch states. S - R flip - flop represents SET-RESET flip - flops .
