Working Principles

SN74ALS166N operates by receiving parallel data through its eight input pins (QA to QH). The shift/load control pin (SH/LD) determines whether the received data is shifted or loaded into the register. When shifting, the clock input (CLK) triggers the sequential transfer of data from one flip-flop to another, resulting in serial data output (QH'). On the other hand, when loading, the parallel data is directly transferred to the outputs upon a positive transition of the SH/LD signal. The master reset (MR) pin initializes the register, while the output enable (OE) pin controls the tri-state output.
