LM2904: Part marking lookup

Grace Chong

Part Number: LM2904

Tool/software:

Hi TI,

I tried to look up the marking information for LM2904DR-JF by using part marking lookup tool, but the result was "No search results found".

Would you mind sharing the reason behind this?

Thank you.

I see the E2E thread below, that this is manufactured by TI based on Carrie's comments. The suffix -JF is a traceability code.

LM2904DR is SOIC-8 standard package.

BTW, LM2904XX parts have issued PCN in recently years. If you see that the post-PCN did not perform identically or check out with pre-PCN LM2904DR, this is not surprising. This is due to the new FAB process and it is known among customers.

If you are looking up the part, search LM2904 instead.

LM2904D-JF is obsolete, see the link below.
