Working Principles

SN74HC595PWR operates based on the principle of serial data shifting and parallel data storage. The SER pin receives serial data, which is then shifted through the shift register upon each rising edge of the SRCLK signal. The RCLK signal latches the shifted data into the storage register, making it available at the parallel output pins (Q0-Q7). The OE pin controls the output stage, enabling or disabling the output signals.
