In these settings, the device’s fault‑protected bus interface is particularly helpful for mitigating common field issues such as wiring faults, transients on the bus, or unexpected environmental stresses.

Design & Integration Notes

• Physical Layer Compliance: The transceiver supports the CAN FD physical layer per ISO 11898‑2, allowing integration with modern controllers that implement CAN FD protocols.
• Power Rail Flexibility: The 1.7 V to 5.5 V operating supply range enables use with a variety of system rails. This can reduce BOM complexity across platforms that standardize on different logic supplies.
• Package and Assembly: The SOIC‑8 (D) package is easy to assemble and inspect, suitable for high‑reliability automotive and industrial production lines. The Tape & Reel (TR) option simplifies automated pick‑and‑place.
• Layout Guidance: Maintain short, symmetric traces to the CANH/CANL bus and follow standard high‑speed layout practices. Differential routing and solid return paths help ensure signal integrity.
• Bus Topology and Termination: ISO 11898‑2 networks typically use 120 Ω termination at each bus end; follow system‑level topology guidance and consult the datasheet for any device‑specific constraints. Keep stub lengths short to minimize reflections.
• Protection and Filtering: The device includes a fault‑protected bus interface; for complete design robustness, complement with system‑level protection (common‑mode chokes, TVS diodes, filtering) as appropriate for your EMC/ESD requirements. Refer to TI application notes and the datasheet for recommended practices.

These considerations can accelerate bring‑up and help ensure compliance with system‑level EMC and reliability targets.
