Hi Team TI,

we ahve bought LM2903DR and now have some doubts.

Could you please confirm according to the immage, that it is your product?

Hello Viachaslau,

#2 is an ST Semi device - not ours.

#1 does not follow any TI conventions - no logo or TI. Is there any markings on the bottom?

#3 is a TI device that follows the new "dot" marking convention and is a valid lot number from Dec 2024.

Hello Viachaslau,

If there is no markings on the bottom, then this is not a TI device.

The lot code is incomplete and does not follow the TI marking convention. I cannot determine the date code.

A TI or National device will have a logo or "TI".

I don't know who it may be...There are dozens of international sources of the LM2903.
