TSS721ADR datasheet by Texas Instruments

TSS721ADR Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  A 2-layer or 4-layer PCB with a solid ground plane and thermal vias is recommended. Ensure a minimum of 1 oz copper thickness and a thermal relief pattern around the device.
• How do I ensure reliable operation in high-temperature environments?
  Implement a heat sink or thermal interface material, and ensure good airflow. Consider using a thermocouple to monitor the device temperature.
• What is the maximum allowed voltage on the input pins?
  The maximum allowed voltage on the input pins is 5.5V, but it's recommended to keep it below 5V to ensure reliable operation.
• Can I use the TSS721ADR in a 3.3V system?
  Yes, the TSS721ADR can operate in a 3.3V system, but ensure the input voltage is within the recommended range (2.7V to 5.5V) and adjust the resistor values accordingly.
• How do I troubleshoot issues with the device?
  Use a logic analyzer or oscilloscope to monitor the input and output signals. Check the power supply voltage, input signal integrity, and output loading conditions.
