SN74HC244NSR Frequently Asked Questions (FAQs)

  • The maximum frequency of operation for the SN74HC244NSR is 40 MHz.
  • Yes, the SN74HC244NSR 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. Connect it to VCC to disable the outputs.
  • The SN74HC244NSR can sink or source up to 25 mA per output pin.
  • Yes, the SN74HC244NSR is compatible with 3.3V systems, but the output voltage will be limited to 3.3V.
