Working Principles

The SN74LS597N is a shift register that allows data to be shifted in serially and then outputted in parallel. It consists of eight flip-flops, which store the incoming data bits. The shift register clock (SRCLK) controls the shifting of data from one flip-flop to another. The register clock (RCLK) latches the input data into the flip-flops, allowing parallel outputs to be obtained. The output enable (OE) signal enables or disables the outputs.
