SN74AHCT244DBR datasheet by Texas Instruments

SN74AHCT244DBR Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74AHCT244DBR?
  The maximum operating frequency of the SN74AHCT244DBR is 100 MHz.
• Is the SN74AHCT244DBR 5V tolerant?
  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.
• What is the propagation delay of the SN74AHCT244DBR?
  The propagation delay of the SN74AHCT244DBR is typically around 10-15 ns, but this can vary depending on the operating conditions and load capacitance.
• Can I use the SN74AHCT244DBR in a 3.3V system with 5V devices?
  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.
• How do I handle the power sequencing of 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.
