SN74F280BN datasheet by Texas Instruments

SN74F280BN Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74F280BN?
  The maximum operating frequency of the SN74F280BN is 100 MHz, but it can vary depending on the specific application and operating conditions.
• How do I ensure signal integrity when using the SN74F280BN?
  To ensure signal integrity, use proper PCB layout techniques, such as keeping signal traces short and away from noise sources, using termination resistors, and minimizing impedance mismatches.
• What is the power consumption of the SN74F280BN?
  The power consumption of the SN74F280BN depends on the operating frequency, voltage, and load. Typically, it consumes around 20-30 mA at 5V and 50 MHz, but can be as low as 1 mA in standby mode.
• Can I use the SN74F280BN in a 3.3V system?
  Yes, the SN74F280BN can operate at 3.3V, but the output voltage will be limited to 3.3V, and the input voltage threshold may be affected. Consult the datasheet for specific voltage and current requirements.
• How do I handle thermal issues with the SN74F280BN?
  To handle thermal issues, ensure good airflow around the device, use a heat sink if necessary, and avoid operating the device at maximum power dissipation for extended periods.
