SN74F1056: SN74F1056DR Differences in product internal structure

user6350528

Part Number: SN74F1056

Dear team

We purchased two batches of products sn74f1056dr, which were manufactured in 2006 and 2021. X-ray detection found that there were differences in the internal framework of the two batches of products. Will this affect its function?Tks

Best regards,

No, the changes will not significantly affect electrical performance.

The device still meets the datasheet defined specifications.

Hi Emrys

Noted.

What are the reasons for these differences?

Different production dates or different places of origin?

I'm afraid I don't know -- with 15 years of separation, many changes can happen.

Are you having some issue with the electrical performance of the device?

Hi Emrys

It is not found that the electrical performance of the equipment has an impact. We often encounter such problems when purchasing TI products. We guess it is due to the origin
