1.
All voltage values are measured with respect to the ground pin.
2.
The magnitude of the input signal must never exceed VCC + 0.3 V / GND - 0.3 V.
3.
The device is protected in case of over temperature by a thermal shutdown active at 150° C.
4.
Human body model: A 100 pF capacitor is charged to the specified voltage, then discharged through a 1.5 k
Ω resistor
between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating.
5.
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 is done for all couples of connected pin combinations
while the other pins are floating.
