Part Number: AM26LS31

From product datasheet AM26LS31, for part rated 0'C to 70'C operating condition which is using copper wire, can it pass High Temperature Operating Life test, HTOL125'C, 1000 hours and Temperature Cycle, TMCL -65'C/150'C, 500 cycles reliability test?

Ewe,

I'll let the RS485 expert comment as well, but given the limited operating condition temperature range, it's unlikely that this device was quality tested to 125C and 150C. Since these are older devices we'll have to dig around for the quality testing information, but more than likely they won't fare well in long term high temperature testing.

Regards,

Eric Hackett

Thanks, Hao. From the qualification summary for AM26LS31CDBR which is also Commercial part (0C to 70'C), the part passed 1000 hours HTOL 125'C and 500 cycles TMCL -65/150'C. Is this based on Copper wire bonding? What is the mold compound type?

Yes, the device has Cooper wire bond. I'm sorry the mold compound type is "TI information", which can not be shared on public forum. However for more material content, please check out this report posted on ti.com: https://www.ti.com/materialcontent/en/report?pcid=8196&opn=AM26LS31CDBR
