SN74AC374DW Frequently Asked Questions (FAQs)

  • The maximum frequency of operation for the SN74AC374DW is 100 MHz, but it can vary depending on the output load and operating conditions.
  • To ensure that the outputs are not corrupted during power-up or power-down, it is recommended to use an external pull-up or pull-down resistor on the output pins, and to use a power-on reset (POR) circuit to initialize the device.
  • The recommended operating voltage range for the SN74AC374DW is 4.5V to 5.5V, but it can operate down to 3.5V with reduced performance.
  • To handle bus contention, it is recommended to use a bus holder or a bus keeper circuit to maintain the last valid state on the bus, and to use a bus arbiter or a bus controller to manage access to the bus.
  • The maximum current that the SN74AC374DW can sink or source is 24 mA per output pin, but it is recommended to limit the current to 12 mA per pin to ensure reliable operation.
