Working Principles

SN74HC166AIDRQ1 operates as a parallel-in/serial-out shift register. It receives parallel data through its 8 input pins and converts it into serial data at the output pin. The clock input controls the shifting of data from one stage to another. The shift/load input determines whether the data is shifted or loaded into the register. The master reset input clears the register, setting all outputs to a low state.
