Working Principles

The MM74HC594N operates based on the principle of serial-in parallel-out shifting. It receives serial data through the SER pin and shifts it through the internal shift register upon receiving clock pulses at the SRCLK input. The parallel data is then available at the Q0-Q7 outputs. The RCLK input is used to latch the parallel data into the output registers, while the OE pin enables or disables the outputs.
