SN74LS280D Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74LS280D?
  The maximum operating frequency of the SN74LS280D is 100 MHz, but it can vary depending on the specific application and operating conditions.
• How do I ensure reliable operation of the SN74LS280D in high-temperature environments?
  To ensure reliable operation in high-temperature environments, it is recommended to follow proper thermal management practices, such as providing adequate heat sinking and airflow, and ensuring that the device is operated within its specified temperature range (-40°C to 85°C).
• What is the recommended power-on sequence for the SN74LS280D?
  The recommended power-on sequence for the SN74LS280D is to apply power to the VCC pin before applying any input signals, and to ensure that the input signals are stable before applying the clock signal.
• How do I handle bus contention when using the SN74LS280D in a multi-master bus system?
  To handle bus contention when using the SN74LS280D in a multi-master bus system, it is recommended to use a bus arbiter or a bus controller to manage access to the bus, and to ensure that only one master device is driving the bus at a time.
• What is the maximum capacitive load that the SN74LS280D can drive?
  The maximum capacitive load that the SN74LS280D can drive is 100 pF, but it can vary depending on the specific application and operating conditions.
