Working Principles

The SN74LS164NSRE4 is a serial-in, parallel-out shift register. It accepts data serially through the SER input and shifts it into its internal storage registers on each rising edge of the CLK input. The shifted data is then available in parallel at the QA to QH outputs. The device operates synchronously, meaning that the outputs are updated simultaneously with the clock signal.
