Other Parts Discussed in Thread: SN75176B

Hello,

Can you please tell me what marking code should be on this part SN65176BPE4?

It seems that multiple parts have different markings. Unfortunately, this information can't be found in the datasheet.

Thank you!

Hi Ioana,

Clemens is correct on the first part of the device markings - however there usually would be a bit more information/ characters on the package which is the lot code information.

If you are talking about the lot code information that should be on the devices (which would be the marking beyond what Clemens shared - as I believe there should be a bit more) that's usually not included in the datasheet - but if you include the part markings in your reply I can look to verify if they are valid parts.

Best,

Parker Dodson

Hi,

Thank you for the information you provided.

Yes, I was looking for the lot code information that should be on the devices.

Marking codes: 21AHP5M and 22A1GJM

Do you have a report/document with this information?

Thank you!

I'm trying to find out if there are any functional differences between those 2.

Footnote (4) says:

There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.

There are no functional differences.

Hi Clemens,

Yes, but I would like to know the exact meaning of every letter/number. It would be easier to understand the issue, I have also found a PCN regarding some changes and this may help.

Thank you!

That information is usually not published because it would be useful to counterfeiters.

Hi Ioana,

The LTC numbers you provided are valid - so they are from TI (i.e. not counterfeits)

There isn't a functional difference between parts with different Lot codes - the information just relates to the lot the device is from + a date code. That's all I can really share on the LTC information.

The parts you have also seem to be after the PCN - however the changes are minimal when it comes to part operation and have been captured in the current datasheet + PCN notice. The main changes are new thermal parameters, and output voltages being set to a max of VCC instead of 6V. This shouldn't cause any major concern for using these parts.

If there is any other issue that you are running into with the part please let me know and I will see what I can do!

Best,

Parker Dodson
