The SN74AS4374BNG4 is commonly used in various digital logic applications, including:

  1. Data storage and transfer in microcontrollers and microprocessors
  2. Address decoding in memory systems
  3. Bus interface control in communication systems
  4. Register control in digital signal processing (DSP) applications
  5. Input/output (I/O) expansion in embedded systems
