TC74HC244AF(F) Frequently Asked Questions (FAQs)

  • The maximum operating frequency of the TC74HC244AF(F) is 50 MHz, but it can vary depending on the output load and operating conditions.
  • It is recommended to power up the VCC pin before the input signals and power down the VCC pin after the input signals to prevent unwanted output states.
  • The recommended operating voltage range for the TC74HC244AF(F) is 4.5V to 5.5V, but it can operate from 3V to 6V with reduced performance.
  • To ensure the output signals are not distorted or skewed, it is recommended to use a low-impedance output load, such as a 1kΩ resistor, and to keep the output traces short and well-terminated.
  • Yes, the TC74HC244AF(F) can be used in a 3.3V system, but the output voltage will be reduced, and the device may not meet the specified propagation delay and output current.
