Limiting values

[1]

An internal clamp sets the supply voltage and current limits.

[2]

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

 series resistor.

[3]

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.
