SN65HVD06: SN65HVD06

Henrik,

I confirmed the  “77M A804” is real TI device SN65HVD06. However I didn't find the other 2 lot trace code markings in the system. Can you provide us a legible topside image of the unit and where/when they purchased it from? 

Regards,

Hao

Hi Hao.
Thank you for the very fast response to my request.

I have added three photos as described in my request.

Please have a look at them.

New part, failing (bought by our supplier, requested information but haven't heard anything yet):

Older, working:

Replacement, working (bought app. 4 years ago at Farnell DK):

Thanks in advance

Henrik Damtoft.

The replacement part, 11M AKF6, was bought at RS Components DK. Not at Farnell DK.
This item was bought app. 4 years ago.

This is a picture of the non-opened ESD bag including 1 pcs. of SN65HVD06DG4 with coding: '11M AFL6'

Hi Hao.
I found something very interesting.
I replaced the 1MHz 2.5V clock input with an external generator and varied the amplitude to verify trigger threshold..
It appears that the A804 has app. 1.8V as trigger threshold at the clock pin.
The AVSU has app. 2.65V...! 
According to datasheet, the threshold is min. 2.0V..!

Supplier information regarding delivery of items:
VP06 92M AVSU: delivered by ALBA Components
VP06 77M A804: delivered by Arrow

I have attached X-ray photos of both IC's and I think they speak for themself.

Henrik,

Thanks for your information. We're investigating this. I will update you when I get feedback.

Henrik,

"77M A804" matches our bonding diagram, however "11M ALF6" material doesn't. It is likely a counterfeit. Here is the information to report it to TI.

Required information

1. Completed Counterfeit Request Form. 

2. High quality pictures of the bottom & top of the device(s)

3. High quality pictures of the 2D bar code labels.  

4. Copies/pictures of shipping documents, i.e. packing slip showing the origin of the devices to TI.  (If this information cannot be provided we are unable to provide verification due to uncertainties regarding chain of custody of the products.)

5. Provide device application.

   Once the required information is provided and submitted, your request will be reviewed for verification.

• Important Note: The attachment size limit for the group address (ti-counterfeit@list.ti.com) is 1MB.  Email lisam@ti.com, and j-davenport@ti.com if your attachments are larger than 1MB.

                        

• TI strongly encourages you to purchase all your TI parts either directly from TI or from authorized TI distributors (http://focus.ti.com/docs/general/distribcountryresults.jhtml) and not from the gray market or brokers.
