SN74HC244N Frequently Asked Questions (FAQs)

  • The maximum frequency of operation for the SN74HC244N is 50 MHz.
  • Yes, the SN74HC244N is compatible with 5V systems, but it can also operate at lower voltages down to 2V.
  • The output enable (OE) pin is active-low, meaning that the outputs are enabled when OE is low (connected to GND) and disabled when OE is high (connected to VCC).
  • The propagation delay of the SN74HC244N is typically around 10-15 ns, but this can vary depending on the operating conditions and load capacitance.
  • Yes, the SN74HC244N can be used as a level shifter, but it's not recommended as it's not designed for that purpose. Instead, use a dedicated level shifter IC for reliable operation.
