Label DC is different from IC marking DC

Hi TI Expert,

Part number DS90UB954TRGZRQ1, there are 2 DC on the label, 2147&2148 also shows 1B&1C, after checking, there is only marking 1C which means year 2021 and month December, but the period of 2 DC 2147&2148 is on November, we could not find 1B on the IC marking.

Please advise is this normal?

Thanks and regards,

Vincent

Hello， where have you bought them? Did you buy them on TI estore? If yes, please provide the order number in convenience to confirm .

In addition, could you please tell me why do you mean there is only marking1C？ I think there is different package site and may be it would have different label, but I need to confirm again.
