SN74AHC244DW Frequently Asked Questions (FAQs)

  • The maximum frequency of operation for the SN74AHC244DW is 100 MHz.
  • Yes, the SN74AHC244DW is compatible with 5V systems, but it's recommended to use a voltage regulator to ensure a stable 5V supply.
  • The output enable (OE) pin is active-low, meaning it should be connected to GND to enable the outputs. Leaving it unconnected or connecting it to VCC will disable the outputs.
  • The SN74AHC244DW can sink or source up to 24 mA per output pin.
  • Yes, the SN74AHC244DW is compatible with 3.3V systems, but the output voltage will be limited to 3.3V.
