About "11898-24V" mentioned in the spec of PCA82C251

[christopher1]

In the data sheet of PCA82C251, a description can be found as "Fully compatible with the "ISO 11898-24V". I tried to find "ISO 11898-24V" in Google, Bing, ISO official website and BAIDU, I cannot find any useful info about it. What is "ISO 11898-24V" is it a standard or some papers / documents?

If somebody know the details for "ISO 11898-24V", could you share some info with me ?

And, I have read all documents in ISO 11898 series. I did not find the answer.

Thanks!

Hi,

I was told that the datasheet will be updated because this sentence is confusing. There's no ISO 11898-24V, of course. It looks like the authors wanted to emphasize that PCA82C251 is compatible with the ISO 11898 and that this device is suitable for 24V system supply.

Regards,

Lukas

Hi, Lukas,

Thank you for your response.

Still, I have confused by PCA82C251 and TJA1057, according to the 11898-2, there is no difference between 12V system and 24V system, and the supply voltage of PCA82C251 and TJA1057 is same, then, what is the real difference between two products, why does NXP release two products according to one standard(11898-2)? I assume, there are some differences between PCA82C251 and TJA1057, which are not mentioned in the standard. And, in practice, some automotive components can work with PCA82C251, but not TJA1057.

Could you share some experience for my upper confusion?

Thanks

Chris.

Hi,

PCA82C251 is old legacy part from PHILIPS period. The production started roughly in 1997. TJA1057 is relatively new part (2013). So, the technology of new TJA1057 is aligned with other transceivers:
