SN74CB3T3306: Device marking

Part Number: SN74CB3T3306

Hi team,

My customer procured SN74CB3T3306DCTR. Top marking should be "WA6 Z" but it shown "WA6 81Z", please clarify.

Beat Regards,
Tom Liu

  • Hi Tom,

    If you look in the Device Marking lookup tool, it shows "WA6" and "Z" as valid device markings for the SN74CB3T3306DCTR.

    I also checked the "WA6 81Z" - this is also valid marking where "8" represents the last digit of the year and "1" represents the month.
