SN74AHC244QPWR datasheet by Texas Instruments

SN74AHC244QPWR Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74AHC244QPWR?
  The maximum operating frequency of the SN74AHC244QPWR is 100 MHz, but it can vary depending on the output load and the system's noise margin.
• How do I ensure signal integrity when using the SN74AHC244QPWR in a high-speed application?
  To ensure signal integrity, use a low-impedance output termination, keep the output traces short and well-matched, and consider using a series resistor to reduce ringing and overshoot.
• Can I use the SN74AHC244QPWR in a 3.3V system, and if so, what are the power supply requirements?
  Yes, the SN74AHC244QPWR can be used in a 3.3V system. The recommended power supply voltage is 3.3V ± 0.3V, and the device can operate with a supply current of up to 20 mA.
• How do I handle the thermal management of the SN74AHC244QPWR in a high-power application?
  To handle thermal management, ensure good airflow around the device, use a heat sink if necessary, and follow the recommended PCB layout guidelines to minimize thermal resistance.
• Is the SN74AHC244QPWR compatible with 5V logic levels?
  The SN74AHC244QPWR is not compatible with 5V logic levels, as it is designed for 3.3V or 1.8V operation. Using it with 5V logic levels may cause damage to the device or incorrect operation.
