All voltages are measured with respect to ground; positive currents flow into the IC. The pin V
current driven. The voltage ratings are valid provided other ratings are not violated. The current ratings are
valid provided the maximum power rating is not violated.
Human Body Model (HBM): equivalent to discharging a 100 pF capacitor through a 1.5 k resistor.
Machine Model (MM): equivalent to discharging a 200 pF capacitor through a 0.75 H coil and a 10
resistor.
