Working Principles

The SN74LS164D is a serial-in, parallel-out shift register. It receives 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 output pins QA to QH. The MR input allows for clearing the register by overriding the stored data with logic low. The QH' output provides an inverted version of the QH output.

Detailed Application Field Plans

  • Serial-to-parallel data conversion
