Part Number: SN65176B

Hi Experts,

referring to the tread: SN65176B: SN65176BDR - Interface forum - Interface - TI E2E support forums

I see that the discussed 2 different die topologies are valid.

I see another third different die topology for SN65176DBR.

Is this topology also valid?

Thank you.

There are three manufacturing sites for the SN65176BDR. This is plausible.

Hi Johann,

Can you please let me know the markings on top of the IC - all the codes would be helpful and I will trace the units to verify.

Best,

Hi Johann,

I was no able to trace the lot code - please confirm if the is 1st Row: 65176B; 2nd Row: 28M; 3rd Row: STK9. If this is correct these units may be counterfeit as I am not finding them in our lot code tracer. If this is the case please see next steps here: https://www.ti.com/support-quality/quality-policies-procedures/anti-counterfeit.html
