ISO1176: Any materials? "

Part Number: ISO1176

Hi,

According to "UL Certification (Rev. O)" https://www.tij.co.jp/jp/lit/pdf/szzq072 , Issue is "Texas Instruments Tucson Corp" as follows.  But UL Product iQ page "https://iq.ulprospector.com/en/" shows "Texas Instruments Incorporated".

   

On the document of my customer's end equipment, "Texas Instruments Tucson Corp" is described.  Do you have any materials that "Texas Instruments Incorporated" is same as "Texas Instruments Tucson Corp"?   He worries that this topic is pointed out by UL.  Please advise us.

Thanks and best regards,
M.HATTORI

  • Hi M. Hattori,

    Thanks for posting your question on E2E forum. 

    Our initial ISO devices were produced and UL certified by Texas Instruments facility in Tucson, Arizona. The Tucson facility used to be a different company, Burr Brown that Texas Instruments purchased a couple of decades ago. Therefore the original location and address is shown on the certificate.

    Please note that no other customer or UL has ever questioned that Texas Instruments Inc owns Texas Instruments Tucson Corp. I hope this answers your question.

  • Hi M Hattori,

    I got further clarification on this topic from our Quality team member who worked on this issue with UL. Following is the feedback summary:

    As many of the device certifications were initiated by different product line teams across different physical locations, the company information often reflected the local address of the requester rather than the corporate headquarters.  We started work with UL in 2019 to consolidate all our certifications under the main Texas Instruments Incorporated account. All their systems and accounting now reflect this naming, thus the listing in the productIQ system.  Newly issued certifications and reports will also reflect this name. 

     However, any edit to an already existing certification or report document generates a fee.  This charge would become rather significant if proactively updating every document for this name correction.  UL and TI agreed to let the existing documents stand as is with the understanding that if/when the documents are updated for a technical reason, the company name correction would be wrapped into that next revision and deflect the unnecessary charge.

    This discrepancy should be a non-issue for any discussions within UL. 

    I hope this clarifies the discrepancy.

    Thanks,
