SN65C3222: 请帮忙判断一下哪个丝印是TI正品Please help to determine which silk screen is genuine TI

Hello,

I cannot read all the characters very clearly on #2.  The markings on #1 do not look valid to me, though - when I check the lot number I don't find any internal records of the lot.  I suggest you follow the instructions here to notify our anti-counterfeit team:

https://www.ti.com/support-quality/quality-policies-procedures/anti-counterfeit.html

Note that TI recommends only purchasing ICs from TI directly or via authorized distributors.  You can locate distributors here: https://www.ti.com/info-store/distributors.html.

Max

Hi，Max

非常感谢您的回复！

Thank you very much for your reply!

能否请你再帮忙辨识一下这个是否属于TI的正品？

Can you please help me identify whether this is a genuine TI product?

另外TI公司有关于产品丝印的说明文件以防消费者买到假货吗？

In addition, TI company has a description document on the silk screen of the product to prevent consumers from buying fakes？

Thank you！

Hello Tao,

Thank you for the clear photo.  This unit has a valid lot code.

We do not publish our lot naming conventions for customer to detect counterfeit ICs.  If we did, the counterfeit IC producers would be able to copy it.  That's why we recommend only purchasing from authorized distributors rather than unauthorized ecommerce or grey market providers.

Best regards,
Max

Hi Max，

请帮忙验证一下SN65C3232EDR是否TI正品。另外想咨询一下SN65C3232DR的ESD（HBM）跟SN65C3232EDR一样都是15KV，SN65C3232DR跟SN65C3232EDR的主要区别是什么？

Please help to verify whether the SN65C3232EDR is a genuine TI, and I would like to consult the ESD (HBM) of SN65C3232DR which is 15KV like SN65C3232EDR. What is the main difference between SN65C3232DR and SN65C3232EDR?

Hello，

Thank you very much for the reply from TI. The problem with this device is temporarily gone. Thanks again!
