Working Principles

SN74LS595DR operates based on the principle of shifting data bits through a register. The serial data input (SER) is shifted into the shift register on each rising edge of the shift register clock (SRCLK). The register clock (RCLK) latches the data from the shift register into the storage register. The parallel outputs (Q0-Q7) reflect the stored data, which can be accessed simultaneously.
