Part Number: SN74AHCT541

Regarding this chip SN74AHCT541, we have received two batches of goods.

However, the printing style on the front of the chip is completely different. Is there a PCN change? What caused it?

2. The style on the back is also different. Is there a PCN change? What caused it?

Hi Alex,

This device can come from multiple assembly sites (labeled ASO on the package). Those assembly sites may apply different top markings to the part either in font, stamp on the back, or even top marking. The DS will include all available top markings for this part.

If a new assembly site is qualified there will be a PCN notifying you of the new site.

Regards,

Owen

Could you please provide the relevant PCN regarding the change in the groove design on the back.
