Alternative sourcing for technical standards.

It is worth noting that some concessions have been made. The rise of CAN FD (Flexible Data-rate) and the push for wider adoption have led organizations to release certain specifications more freely. Manufacturers of CAN controllers (like Microchip, Texas Instruments, and NXP) often provide extensive application notes and datasheets that paraphrase the ISO standard, providing engineers with the necessary implementation details without requiring them to purchase the original document. This workaround has become the de facto standard for many: don't read the law (ISO); read the lawyer's summary (the datasheet).

Both CAN_High (CAN_H) and CAN_Low (CAN_L) lines are biased to approximately 2.5V. The differential voltage ( ) is close to 0V. iso 11898-2 pdf download

While ISO 11898-2 specifies a maximum bit rate of , the actual achievable speed depends entirely on the bus length due to propagation delays: 40 meters: Up to 1 Mbps 100 meters: Up to 500 kbps 500 meters: Up to 100 kbps 4.

If you are looking to purchase a transceiver, I can help you:

ISO 11898-2 is primarily used by hardware engineers, transceiver chip designers, and ECU manufacturers. As of 2024, major semiconductor companies like NXP, Infineon, STMicroelectronics, and Bosch are producing chips that comply with the new SIC and XL standards to meet the demands of next-generation vehicles.

A: Only if you are implementing CAN SIC XL transceivers or need the 20 Mbit/s FAST mode . If your system runs classic CAN or standard CAN FD, the 2016 version remains technically valid, though the older editions (2003, 2016) are now designated as "withdrawn" by official standardization bodies.
