ISO1410DWEVM: High temperature RS-4xx chips

Part Number: ISO1410DWEVM
Other Parts Discussed in Thread: SN65HVD11-HT

I need a high temperature package with robustness similar to ISO1410DW. Tolerance to sustained temperatures above 250C will be necessary. Does this exist?

    Hi Ben,

    Thank you for posting, and welcome to E2E! Unfortunately TI does not offer isolated devices that can tolerate sustained ambient temperatures above 150C. Is your end product expected to operate in ambient temperatures above 250C or are you looking for devices that can withstand internal heating over 250C during operation?

    Please also let me know if isolated RS-4xx chips are necessary or if standalone transceivers could be acceptable.


    Respectfully,

    Hi Manuel,

    We are looking to operate in 250C ambient temperatures, unfortunately. I have found SN65HVD11-HT, and we should be able to make that work for the time being even though it is not isolated. Isolation is not critical, but we do need to go to 250C eventually so any advice would be appreciated. 

    Thanks

    Ben

    Hi Ben,

    I understand. SN65HVD11-HT is the device I recommend for this case, but we do not have alternate devices to support operation in such high temperatures.

    May I send you a Personal Message and ask for details of this application?


    Thank you,
