This is something I didn't know. Learned some new things today.
That's problably the reason why Atmel gives the max voltage at Vd + .3V.
If You go higher You could have "Latch up"
I assume Vd is the voltage of the battery or the power supply. So if we have a 3.0V power supply the max input voltage would be 3.3V. If we have 3.6V power supply the max input voltage would be 3.9V.
Am I correct or did I miss something ?
