Shift registers are classified under four types, namely: Although in many of the commercial shift register ICs their internal circuit diagram might indicate the use of R-S flip-flops, a careful examination will reveal that these R-S flip-flops have been wired as D flip-flops only. The basic building block in the shift register is the flip-flop, mainly a D-type flip-flop. The data to be stored could be the data appearing at the output of the flip-flop. A shift register consists of an array of flip-flops connected in cascade.Ī shift register is a digital device used for storage and transfer of data.
