Working Principles
SN74ALS165N operates by receiving parallel data through its DS pins. The shift/load control input (SH/LD) determines whether the received data is shifted or loaded into the internal register. When the clock input (CLK) transitions from low to high, the data is shifted serially out of the QH' pin. The master reset input (MR) resets the internal register to its initial state.
