Instructions for TJA1040/C

1. Power Supply:

   • Ensure the supply voltage (V_CC) is within the range of 3.0V to 5.5V.
   • Use a stable power source to avoid voltage fluctuations.

2. Grounding:

   • Connect the ground (GND) pin to a common ground point to ensure proper operation and signal integrity.

3. Input and Output Connections:

   • Connect the input signals to the appropriate input pins (IN+ and IN-).
   • Connect the output signals to the differential output pins (OUT+ and OUT-).

4. Operating Temperature:

   • The device operates reliably within the temperature range of -40°C to 125°C. Ensure adequate heat dissipation if operating near the upper limit.

5. Data Rate:

   • The maximum data rate is 1.0 Mbps. Ensure the differential output swing is at least 0.8Vpp for reliable communication.

6. Common-Mode Input Voltage:

   • The common-mode input voltage range is from -2V to 14V. Ensure the input signals do not exceed these limits to prevent damage.

7. Overvoltage Protection:

   • The device has overvoltage protection up to 40V. However, it is recommended to use external protection circuits for voltages exceeding the typical operating range.

8. ESD Protection:

   • The device has built-in ESD protection up to 4000V (Human Body Model). Handle the device with care to avoid static discharge.

9. Short-Circuit Protection:

   • The device has a short-circuit current limit of 30mA. In case of a short circuit, the device will limit the current to protect itself.

10. Thermal Shutdown:

    • The device will automatically shut down if the temperature exceeds 165°C. Ensure proper cooling and ventilation to prevent thermal shutdown.

11. Storage:

    • Store the device in a dry environment within the temperature range of -65°C to 150°C to maintain its performance and reliability.

12. Mounting:

    • Follow standard surface mount technology (SMT) procedures for mounting the device on a PCB. Ensure proper soldering and alignment to avoid mechanical stress.

13. Testing:

    • After assembly, test the device under normal operating conditions to ensure it meets the specified parameters and performance criteria.
