SN74AC245DW Frequently Asked Questions (FAQs)

  • The maximum frequency of operation for the SN74AC245DW is 100 MHz.
  • Yes, the SN74AC245DW is compatible with 5V systems, but it can also operate at 3.3V or other voltage levels with proper voltage translation.
  • The direction control pins (DIR) should be connected to a logic level (VCC or GND) to enable or disable the direction of data flow. Leaving them floating can cause unpredictable behavior.
  • The propagation delay of the SN74AC245DW is approximately 10 ns, but this can vary depending on the operating frequency and voltage.
  • Yes, the SN74AC245DW can be used as a level shifter, but it's not recommended as it's not designed for that purpose. Instead, use a dedicated level shifter IC for reliable operation.
