CD4069UB: Is it original Texas IC?

Luca Peterlini

Part Number: CD4069UB

We are having issues with this IC and in some boards it's locked on low level output when input is also low.

Power supply is 3.31 volts.

There is quite a few with this problem.

Could TI tell me something about this lot (IC picture below) 19JMAK4 G4?

Is it original?

Thanks.

Hey Luca,

If you feel that this may be a counterfeit I would recommend contacting our customer support team who can direct this issue to a team more dedicated to handling this sort of claim

We encourage you to purchase all TI semiconductor products either directly from TI or through a TI-authorized distributor.

Thanks,

Rami,

we have our boards mounted with another company and they should buy only from official distributors but sometimes is difficult to monitor it.

Anyway, thanks for your help on this matter. I'll be contacting TI support to clarify this.

Best regards.
