TPS7A47: Question about mixed date code within the reel.

George Hoang

Part Number: TPS7A47

Hi,

I have a reel of TI P/N TPS7A4700RGWR that seems to have 2 different Date markings within the reel. Is this normal?

And we have the following markings

As far as I know, work days for week 26 run from Monday June 27th to Friday July 1st, could this explains the different in the markings above from the reel?

Thank you in advance.

George.

Hi George,

This is a possibility if the devices in the package came from a different wafer lot, however I will have to check with some of our marketing engineers to see if this is possible for the device.

Additionally, our date codes are not publicly listed information on the die markings, So I am curious to know how you've derived the markings do not align with the date code on the label.

Regards,

John

Thank you for checking in about this.

To answer your question, there are a lot of posts in this forum about date code and I read through them, although I couldn't find answer to my question since each of the post I found are pointed to different issues.

Thanks George,

I don't think that this is a problem at this time, but if I hear back from our team and they do have concerns I will be sure to notify you

Hi George,

I spoke with the manager and he does not see a concern with the devices that you have presented in the post, thanks for your patience.
