AM3351: Fail-safe IOs

Part Number: AM3351

Hi,

customer checks use case, that on a non supplied IO bank of AM335,1 ~2V DC with max 3mA is applied.

- Is customers use case OK and inside specs ?

- In DS max ratings Latch Up Perfomance is given with 45mA. What exactly does it mean  ?

- If something inside AM335 will be damaged (backpowering 2V, max 3mA), can we describe worst case scenario ?
