Texas Instruments recommends following a star-grounding topology, keeping analog and digital grounds separate, and using a solid ground plane to minimize noise. Additionally, keep the input and output traces short and away from each other to reduce crosstalk.
Verify that the supply voltage (VCC) is within the recommended range of 2.7V to 5.5V, and the input voltage (VIN) is within the recommended range of 0V to VCC. Also, ensure that the device is operated within the recommended temperature range of -40°C to 125°C.
To power down the TLC372QDR, bring the SHDN pin low. This will put the device into a low-power shutdown mode, reducing the quiescent current to typically 1 μA. Note that the device will retain its output state when shut down.
Start by verifying the power supply and input voltage levels. Check for proper connections and routing of the input and output signals. Use an oscilloscope to monitor the input and output waveforms. If issues persist, consult the Texas Instruments support resources or contact their technical support team.
Yes, in high-reliability or safety-critical applications, consider using redundant circuits, implementing error detection and correction mechanisms, and following relevant industry standards and guidelines (e.g., IEC 61508 or ISO 26262). Additionally, ensure that the device is properly derated and that the system is designed to tolerate single-point failures.
