MAX3232E: Need higher ambient temperature solutions!!!

Part Number: MAX3232E
Other Parts Discussed in Thread: TRS3232E-Q1

Hi team,

My customer designs Outdoor AP application. And their ambient temperature will be up to 95'C at least.

So do we have similar function solution with higher TA specification? Please suggest.

Thanks

  • Paul,

    While the ambient temperature rating is less than 95C, the device can withstand up to 150C junction temperature without damage. That being said, with 95C ambient, and thermal resistance characteristics of this device, this may be a risk.

    There are automotive rated and extended protection RS-232 transceivers which are rated up to 125C ambient. The TRS3232E-Q1 is an example, and would serve the same functionality for the customer. 

    To find more RS-232 transceivers that could fit the customer's needs, search for RS-232 transceivers on TI.com and filter by operating temperature range.

    Regards,
