The NXP Semiconductors TJA1040T/CM,118 is a high‑speed CAN transceiver designed for robust, standards‑based connectivity in automotive and industrial systems. As part of the TJA1040 series, this device implements the physical layer of a Controller Area Network (CAN) compliant with ISO 11898‑2 and supports data rates up to 1 Mbps. Supplied in a compact SOIC‑8 package and shipped on tape‑and‑reel, the TJA1040T/CM,118 is a practical drop‑in choice for production environments where surface‑mount assembly and consistent, repeatable handling are essential.

Engineers, buyers, and sourcing teams will appreciate the balance of proven CAN interoperability, straightforward design‑in, and reliable NXP supply chain documentation. If your design needs a 5 V, ISO 11898‑2 high‑speed CAN physical layer for a single channel (1 Tx / 1 Rx), the NXP TJA1040T/CM,118 offers a clean, standards‑based path to implementation.

What the TJA1040T/CM,118 Is—and Where It Fits

The TJA1040T/CM,118 is the physical‑layer interface that sits between a CAN protocol controller (in your MCU or standalone controller) and the two‑wire CAN bus that links nodes across a vehicle, machine, or building. In ISO 11898‑2 networks, the transceiver converts logic‑level transmit (TxD) and receive (RxD) signals to differential voltages on the CANH and CANL lines and vice versa, ensuring proper signaling levels and bus compatibility at up to 1 Mbps.

Typical Applications

The NXP TJA1040T/CM,118 is suited for networks that rely on a high‑speed CAN physical layer. Common use cases include:

• Automotive CAN networks
• Industrial automation and control
• Building automation

These environments benefit from the deterministic, differential signaling characteristics of high‑speed CAN, the widespread availability of compatible controllers, and the extensive ecosystem of software stacks and diagnostic tools built around ISO 11898‑2.

How It Fits in a CAN Node (Conceptual Overview)

This section provides general guidance for ISO 11898‑2 networks. It is not a substitute for the TJA1040 datasheet and makes no claims about features not explicitly stated above.

• Placement in the stack: A typical node contains an MCU with an internal or external CAN controller. The CAN controller interfaces to the NXP TJA1040T/CM,118 transceiver, which then drives the bus lines (CANH, CANL).
• Signaling domain: The controller exchanges logic‑level Tx/Rx with the transceiver; the transceiver converts these to differential levels on the CAN bus per ISO 11898‑2.
• Bus topology: High‑speed CAN is typically wired as a linear bus with terminations at the extremes. Exact termination values, common‑mode components, and EMC filters should follow ISO 11898‑2 and application‑specific guidance; consult the NXP datasheet and your system requirements.
• Power domain: Designs commonly power high‑speed CAN transceivers from a regulated 5 V rail. Ensure the rail meets the electrical tolerances in the datasheet and consider system‑level protection appropriate to your environment.

Design‑In Considerations (General Best Practices)

The following points are industry‑standard practices for ISO 11898‑2 high‑speed CAN networks and are provided to streamline your planning. They are not device‑specific guarantees.

• Layout discipline: Keep the CANH/CANL differential pair routed together with controlled impedance where practical. Minimize stubs to reduce reflections.
• Termination strategy: Terminate the bus only at its two ends in high‑speed CAN systems. Choose termination components according to your overall EMC and power‑up behavior goals; consult ISO 11898‑2 and your system design guides.
• Grounding and reference: Provide a low‑impedance return path between node grounds to help the transceiver maintain the required common‑mode range under real‑world transients.
• EMC considerations: If your environment is noisy, evaluate common‑mode chokes, split termination, and transient protection devices as appropriate for ISO 11898‑2 systems.
• Power sequencing and supervision: Ensure the 5 V supply quality and any brownout or reset strategy align with the transceiver and controller’s operating requirements.

Always validate on your target PCB with the exact cable lengths, terminations, and environmental conditions your product will encounter.
