1. Calculated with Tj =+150 °C and Tamb =+25 °C with relative Rthja depending on the package.
2. Human body model: A 100 pF capacitor is charged to the specified voltage, then discharged through a
1.5 kΩresistor between two pins of the device. This happens for all couples of connected pin combinations
while the other pins are left floating.
3. Machine model: A 200 pF capacitor is charged to the specified voltage, then discharged directly between
two pins of the device with no external series resistor (internal resistor < 5 Ω). This happens for all couples
of connected pin combinations while the other pins are left floating.
4. Charged device model: all pins and the package are charged together to the specified voltage and then
discharged directly to the ground through only one pin. This happens for all pins
