Working Principles

SN74HC595MPWREP operates by receiving serial data through the SER pin, which is then shifted into an internal shift register on each rising edge of the SRCLK input. The parallel output values are latched onto the QA-QH pins when the RCLK input transitions from high to low. The output enable (OE) pin allows the outputs to be enabled or disabled, while the shift register clear (SRCLR) pin clears the shift register.
