Working Principles

The DM74ALS165MX is a serial-in, parallel-out shift register. It accepts data serially through the SER pin and shifts it into its internal storage register on each rising edge of the CLK input. The shifted data can then be accessed in parallel through the QH' and QH outputs. The register can be cleared using the MR pin, and the output can be tri-stated using the OE pin.
