Design Notes
Place the SN65HVD234DR close to the CAN bus connector to minimize trace length and reduce EMI. Use a 100 nF decoupling capacitor close to the VCC pin and a 10 µF bulk capacitor on the power rail. Ensure a solid ground plane under the device to provide a low-impedance return path for high-frequency currents.
Do not forget to terminate the CAN bus with 120 Ω resistors at both ends. Incorrect termination leads to signal reflections and communication errors. Also, ensure the RS pin is properly biased: high for sleep mode, low for normal operation. Leaving RS floating can cause unpredictable behavior.
The SN65HVD234DR has a maximum junction temperature of 150°C. In normal operation, power dissipation is low (typically <100 mW), but in fault conditions, the bus pins may dissipate more. Ensure adequate copper area on the PCB for heat sinking, especially in high-temperature environments. The SOIC-8 package has a thermal resistance of approximately 150°C/W.
