Working Principles

SN74LV164APWR operates based on the principles of sequential logic. It receives serial input data through the SER pin and shifts it through its internal registers using the SRCLK (Shift Register Clock) signal. The RCLK (Register Clock) signal is used to latch the shifted data into the output registers. The OE pin controls the output enable function, allowing the parallel outputs to be enabled or disabled. A reset signal can be applied to clear the internal registers and set the outputs to a known state.
