  • Lack of built-in error detection or correction mechanisms.

Working Principles

The M74HC166RM13TR operates based on the principle of shifting data through a series of flip-flops. The serial data input (DS) is shifted into the first flip-flop with each rising edge of the shift clock input (SHCP). The shifted data is then transferred to the output registers by activating the storage clock input (STCP). The master reset input (MR) can be used to reset the shift register to its initial state. The output enable input (OE) controls the tri-state outputs, allowing for the data to be driven onto the output pins or disconnected from them.

Detailed Application Field Plans

The M74HC166RM13TR can be used in various applications, including but not limited to:

  1. Data communication systems
  2. Serial-to-parallel data conversion
  3. Digital displays and LED matrices
  4. Industrial automation and control systems
  5. Automotive electronics
  6. Robotics and motion control systems
