SN74HCT244DW Frequently Asked Questions (FAQs)

  • The maximum frequency of operation for the SN74HCT244DW is 40 MHz.
  • Yes, the SN74HCT244DW is compatible with 5V systems, but it's recommended to use a voltage regulator to ensure a stable 4.5V to 5.5V supply voltage.
  • The output enable (OE) pin is active-low, meaning it should be connected to GND to enable the outputs. If left unconnected, the OE pin will float high, disabling the outputs.
  • The SN74HCT244DW can sink or source up to 6 mA per output pin, with a total current limit of 100 mA for all outputs combined.
  • No, the SN74HCT244DW is not compatible with 3.3V systems. It's designed to operate at 4.5V to 5.5V supply voltage.
