Working Principles

The CD74AC164MG4 is a serial-in, parallel-out shift register. It accepts data serially through the SER pin and shifts it into the register on each rising edge of the CLK input. The shifted data is then available in parallel at the QH' output and the parallel outputs (QH to QC). The OE pin can be used to enable or disable the outputs, while the MR pin allows for a master reset of the register.
