Hello Tony,
I'm not able to confirm the "2M08AC" date code. Date codes follow a YYWW (Year-Year-Week-Week) format on the package label. Are you able to take a picture and share it?
I can confirm the date code was slightly changed in 2014 from the YYWW format to YYWW+5. This increased the shelf life of the DS90LV047A to 5 years.
Regards,
Josh
Chip marking First line print: 2M08AC Can you confirm the date code based on this?
Hello Tony,
The first 2 symbols refers to the Year and Month. "2" stands for 2002 but "M" is not a symbol we use. Can you help us verify the marking by sending us a picture?
Please see the image below for the correct format. Additional information can be found here.

Josh
