CD4047B: Date code 2AC7VFM

Part Number: CD4047B

Tool/software:

Hello,

We are using CD4047B with date code 2AC7VFM. I see that the "2" would be least significant digit in Year and "A" is October. How can we know if the year is 2022, 2012, or 2002? Are there any known quality issues or reports on that specific specific date code?
