Hi Team,

I have a question regarding the marking of PCN#20240203000.0.

In the case of SN74AHC1G08QDCKRQ1, from which datecode was the marking changed?

If you know the changed Datecode, please let me know.

Also, could you please provide images of the old and new markings for SN74AHC1G08QDCKRQ1?

Best regards,

Hi,

Datecodes are the not the same across devices, there is not 1 specific picture I can send of it.

In the PCN there is an example already shown:

The PCN states that both pin 1 markings are now valid, stripe (top row) or dot (bottom row).

Hi Albert-san

Thanks for your reply.

I apologize again and again.
Could you please tell me which DC has the marking changed only SN74AHC1G08QDCKRQ1?
I would like to receive information so that the customer can change the marking reading settings based on the DC information.

Best regards,

Hi,

There should be a device list in the PCN stating what devices + packages are changed. If it is not listed, the PCN should not affect it.

Hi Albert-san

Thanks for your reply.

I got an image of SN74AHC1G08QDCKRQ1 which was in stock.

Is this image before PCN ?
(Pin One Stripe only)

Hi Gk,

There is no way to know for sure from just a picture. The PCN just says that the marking can be a stripe OR a dot.

Hi Albert-san

I apologize for the poor question.

Is it correct to understand that originally it was striped only, as shown in the image?

Best regards,

Hi GK,

Yes you are correct. Originally it was only striped, but now there can be both.
