Limiting values

[1]

[2]

An internal clamp sets the supply voltage.

[3]

Human body model: equivalent to discharging a 100 pF capacitor through a 1.5 k

 series resistor.

[4]

Charged device model: equivalent to charging the IC up to 1 kV and the subsequent discharging of each

pin down to 0 V over a 1

 resistor.
