SN74AHCT244DBR Frequently Asked Questions (FAQs)

  • The maximum operating frequency of the SN74AHCT244DBR is 100 MHz.
  • Yes, the SN74AHCT244DBR is 5V tolerant, meaning it can accept input voltages up to 5.5V even though its recommended operating voltage is 3.3V.
  • The propagation delay of the SN74AHCT244DBR is typically around 10-15 ns, but this can vary depending on the operating conditions and load capacitance.
  • Yes, the SN74AHCT244DBR can be used in a 3.3V system with 5V devices, but you'll need to ensure that the 5V devices are 3.3V tolerant or use level translators to avoid damage to the SN74AHCT244DBR.
  • It's recommended to power up the SN74AHCT244DBR after the power supply has stabilized, and to ensure that the input signals are stable before applying power to the device.
