Working Principles

The MM74HCT164SJX operates based on the principle of shifting data from the serial input (SER) to the parallel output (QH). When a clock pulse is applied, the input data is shifted through the internal shift register, and the converted parallel data is available at the output pins. The master reset (MR) input can be used to clear the register to a known state.
