74ACT244M Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the 74ACT244M?
  The maximum operating frequency of the 74ACT244M is typically around 100 MHz, but it can vary depending on the specific application and operating conditions.
• How do I handle the power-up and power-down sequencing of the 74ACT244M?
  It is recommended to power up the VCC pin before the input signals, and power down the VCC pin after the input signals. This ensures that the device is properly initialized and avoids any potential latch-up or damage.
• What is the recommended termination scheme for the 74ACT244M?
  The recommended termination scheme for the 74ACT244M is to use a series resistor (Rs) of around 22-33 ohms, followed by a parallel capacitor (Cp) of around 10-20 pF, to match the impedance of the transmission line and minimize reflections.
• Can I use the 74ACT244M in a 3.3V system?
  Yes, the 74ACT244M is compatible with 3.3V systems, but it is recommended to check the specific voltage tolerance and operating conditions to ensure proper operation.
• How do I handle the thermal management of the 74ACT244M?
  The 74ACT244M has a maximum junction temperature of 150°C. To ensure proper thermal management, it is recommended to provide adequate heat sinking, use a thermal pad or heat spreader, and keep the device away from high-temperature sources.
