MC74HC244ADWG Frequently Asked Questions (FAQs)

  • The maximum operating frequency of the MC74HC244ADWG is 40 MHz.
  • Yes, the MC74HC244ADWG 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 should be connected to a logic low (GND) to enable the outputs. If left floating, the outputs will be in a high-impedance state.
  • The MC74HC244ADWG can sink or source up to 25 mA per output pin.
  • The MC74HC244ADWG is rated for operation up to 125°C, but it's recommended to derate the device for reliable operation above 85°C.
