I have two Due boards
One from RS the other a clone from geeetech
Both have the 74LVC1G125 near the power connector like your bad type.
The Clone you can clearly see the copper loop from pin 1 to pin 2

The Real Due from RS Pin 1 is not looped to pin 2. But is connected to a ground plane.

The both say "Board Model DUE R3" on the silkscreen underneath..
