MC74HC244ADTG Frequently Asked Questions (FAQs)

  • The maximum operating frequency of the MC74HC244ADTG is 40 MHz.
  • Yes, the MC74HC244ADTG 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. Leaving it unconnected or connecting it to VCC will disable the outputs.
  • The propagation delay of the MC74HC244ADTG is typically around 10 ns, but it can vary depending on the operating frequency and load capacitance.
  • Yes, the MC74HC244ADTG can operate in a 3.3V system, but the output voltage will be reduced to around 3.3V. Ensure that the receiving device can handle the reduced voltage.
