74AC11244: Marking of this buffer and line driver - Mouser SO# 432675

Part Number: 74AC11244

Hello,

can you please advise on the marking of delivered parts P/N: 74AC11244DW ?

A customer claims delivered parts to have a date code of 1101 and 1019, based on the first line part markings:

11D8GPT and 05CQJST...

I have my doubts that this is correct since we received the parts directly form TI with date code 1506...

Could you please tell, if the first line marking has any encoding regarding a date code at all? Could you provide a decoding table for the first line marking in this case, please?

THank you very much.

Best regards

Adnan

 

  • Hi Adnan,
    The topside marking should be:

    <TI logo> YMLLLLS
                    AC11244
                    G4
    O

    Y = year
    M = month
    LLLL = lot trace code
    S = assembly site
    O = pin 1 marking location

    Hello Emrys,

    many thanks for the response. This is according to TI's standard marking guidelines.

    So would this mean that the parts pictured below are already from 2010, respective 2011, or is this a misconception?

    Would such old parts still be usable?

    THank you very much.

    Best regards
