LMV321: Datasheet question on LMV321IDCKR

Frank Lam

Part Number: LMV321

Hi Team,

Was researching the top marking of LMV321IDCKR from the latest version of datasheet "SLOS263X" and noticed this information (See the attached screenshot). Could you please help to verify if it's a typo?

Thank you.

BR,

That information is correct. The LMV321IDCKR is made at three assembly sites, which use different lead finishes. One of the sites uses pure tin; the devices made at this site are also sold as LMV321IDCKRG4.

(The G4 suffix does not mean anything; see [FAQ] Why does a logic device's part number have an E4/G4 suffix?)

Hi Clemens,

Good Day,

Thank you for following up and sharing the info. I have one more question regarding E4/G4 suffix, I got this information from TI website related to lead finish.

Lead finish materials listed under e4 did not include Tin (e3). Would it be odd if Tin finish is also sold as LMV321IDCKRG4?

Thank you.

"E4" and "G4" are different. I would have thought that G4 were more strict than E4, but that is apparently not the case.
