Working Principles

The 74HCT597D/AUJ operates by receiving serial data through the SER pin. The data is then shifted into the shift register on each rising edge of the SRCLK (Shift Register Clock) signal. The input latches hold the data until the RCLK (Register Clock) signal is triggered, at which point the parallel data is transferred to the output pins (QA-Q7). The OE (Output Enable) pin can be used to enable or disable the output buffers.
