LM5110: pins 5 of the DPR package: Not Connected or Do Not Connect?

Casper van Doorne

Part Number: LM5110

Hi All,

In the LM5110 datasheet, it says that pins 5 and 6 of the DPR package are "Not Connect". The term "Not Connect" does not tell me that I must leave the pin floating ("Do Not Connect") or that I could tie it to GND or any other signal ("Not Connected").

Q1) Are pins 5 and 6 of the LM5110-1SD bonded to the die internally ("Do Not Connect") or are they truly not connected ("Not Connected")?

Q2) Would it be possible for TI to standardize this description to either "Do Not Connect" or "Not Connected"? The term "No Connect" is too ambiguous for this purpose.

Cheers,

Casper van Doorne

    Those pins are not bonded to the die, you can either ground or leave floating

    Generally, the following is the standard:
    "Not connected" means not bonded to the die, so you can float or ground the pin without affecting the IC function. Otherwise, the datasheet will explicitly call out if there is a specific requirement.

    Hi Dimitri,

    Thanks for your reply.

    Nice!, Just drop me a DM, I'll send you a card. My previous company was Doofenshmirtz Evil Inc., I'll send you one of those as well.

     

    Thanks for helping me out, I know now that I can use these pins to improve the PCB lay-out.

    Cheers!
