The voltage range

Hi all,

I have a question on the range of the voltage for Power and
Gnd clamps. The question is why do we need such wide range.

Is it not true that on an actual PCB, even if the voltage
at any pin tends to go higher than Vcc (due to L-C
effects etc.), the clamping diodes will allow it to go only
till Vcc+Vf, where Vf is the forward voltage of the clamping
diode? Basically that's what the diodes are for.

What is going to happy if we do provide that wide range of
data? Is it going to fail on QC check?
