Original question:

SN75DP159: Device date code from the device top marking

ISO1050: Need to know know the date code

Part Number: ISO1050

I need to know the date code for traceability for components I have in house.

I don't know how to decipher the date code.  The markings on the top of the component are:

ISO1050

TI CPS7

13K G4.

Thank you for your help in this.

    Hi Leanne,

    Thank you for reaching out to us!

    Four characters in the first line indicate the part number. You could use this link to look up the TI part number.

    https://www.ti.com/packaging/docs/partlookup.tsp

    The four-digit code that comprises the second line of the marking is a unique lot trace code so that TI can better trace the assembly lot.

    The three characters on the third line are (in order) the last digit of the year of assembly, the month of assembly (with 1 = January, 2 = February, ..., A = October, B = November, etc.), and the assembly site.

    ‘G4’ indicates NiPdAu finish on the component and use of “green” mold compound. More information on this can be found from the link below.

    So, specifically for this date code, CPS7, the "C" represents December, and the last digit "7" represents 2017? 

    The attachment does not decode the date code, and typically date codes on the CofC report date codes as week and year (WWYY), eg. 2221.

    Hi Leanne,

    I'm sorry that there was a typo of repeating the second line twice.

    CPS7 is the TI internal lot trace code.

    The third line consists of the year and month information. The first digit is year, the second digit is month, and the third digit is the assembly site.

    Hence, 13K means

    1 : 2011 or 2021

    3:  March

    K: Assembly site.

    Regards,

    Alfred
