Part Number: SN74LVCH16373A

Tool/software:

Hello Support,

I have some questions regarding marking on your TI part numbers.

I can define part marking from your website but i have problem how to determine lot number or date code as compare to distributor's C of C and from actual marking on the part number.

Could you please determine marking for each part numbers below to identify date code or lot number for these product?

If there is information about your trace code or marking about date code, please provide it to me.

1) PN# SN74LVCH16373ADGVR

- Date code from distributor: March-2023

- Actual marking on part: 33C35LK

2) TLV320AIC33IRGZT

- Date code from distributor: 2211

- Actual marking: 23WZ11L

3) PN# LM92CIM

- Date code from distributor: 2309

- Actual Marking: 3344

    Hi Jaden Nam,

    I can confirm that the markings on the SN74LVCH16373ADGVR say that the date code is March-2023. However, I cannot provide marking codes.

    I can provide information about the SN74LVCH16373ADGVR, but the other two belong to different teams. I'll direct this message to the party responsible for the TLV320AIC33IRGZT first.

    Regards,

    Nikki

    Hello Jaden, 

    Let me verify the lot code with my backend team. Do you happen to have the packaging for the reel for the LM92CIM? It should have the lot trace code on it too.

    Regards,

    Harry

    Hi Harry

    For PN# LM92CIM, we dont have packaging for the reel as it was cut tape of 10 pieces we purchased from Arrow.

    We only have packing slip from Arrow showing date code: 2309 with photo with marking: 3344 which i cannot determine date code based on marking.

    Please advise,

    Hello Harry

    I have one more part number and picture showing marking to verify date code.

    For PN# SN65HVD1050MDREP, we received with Arrow's packing slip showing date code: 2142M and below is marking for actual product we received.

    Could you please verify if this marking has date code: 2142M?

    I would also like you to check how to trace date code based on TI marking as lots of TI part does not have date code marked on the actual part.

    Instead it has lot trace code which I cannot determine.

    Hello Jaden, 

    I confirmed with our team that the date code for the LM92CIMX/NOPB is March 2023. I'm going to forward your other date code request to the appropriate team.

    The top marking show 1AT

    1 = 2021 (or could be earlier like 2011 or 2001, with just this information it's not a 100% way to figure it out)

    A = October

    T = Taiwan assembly

    Date code= 2021 42 = 42nd week = October 2021

    The date code from the slip matches the date code from the top marking.

    This is not possible for you to do. TI has an internal server that stores the lot trace codes inorder to find the geneology of the device. Customers do not have access to this.
