This On Semiconductor part:

https://www.onsemi.com/pub/Collateral/NCV8402D-D.PDF

is described in the literature as the NCV8402D/AD. It doesn't describe the difference between the D/AD so far as I can tell. Also, it shows the orderable part number to be NCV8402DDR2G but does not describe what the DR2G means - SOIC package? Lead free? Tape?

I've only inferred two things:

  • The first D after the 8402 means dual, because it's a dual driver - this is made obvious when comparing to other drivers in the series such as the single 8402A
  • Only the AD version is in production, because the D version is listed as obsolete on DigiKey

I'd like to nail this down so that I can properly enter it in my CAD land pattern.

The datasheet seems to indicate that there is only one available package and so only one pinout for either part number. I would think that is all of the information you need for PCB CAD.
