Working Principles

The 74HCT164DB,112 is a serial-in, parallel-out shift register. It receives data serially through the SER pin and shifts it into the register on each rising edge of the clock pulse applied to the CP pin. The shifted data is then available in parallel form at the QA to QH output pins. The MR pin allows for asynchronous clearing of the register, resetting all outputs to a low state.

Detailed Application Field Plans

The 74HCT164DB,112 can be used in various applications that require serial-to-parallel data conversion. Some potential application fields include:

  1. LED Display Control: The shift register can be used to control multiple LEDs, allowing for dynamic patterns and animations.
  2. Data Storage: It can be utilized as part of a memory system for temporary storage of data during processing.
  3. Serial Communication: The device can be employed in serial communication protocols to convert incoming serial data into parallel format for further processing.
