Working Principles

The SN74ALS164ADG4 is a serial-in, parallel-out shift register. It accepts data serially through the SER input and shifts it into its internal register on each rising edge of the CLK input. The shifted data is then available in parallel at the output pins QA to QH. The shift register can be reset asynchronously by applying a low level signal to the MR (Master Reset) pin.

Detailed Application Field Plans

  • Serial-to-parallel data conversion
  • Data storage and retrieval
  • LED matrix control
  • Digital signal processing
  • Communication systems
  • Industrial automation
