1. All voltage values are measured with respect to the ground pin.
2. The magnitude of input signal must never exceed V_CC + 0.3 V / GND - 0.3 V.
3. The device is protected in case of over temperature by a thermal shutdown activated at 150° C.
4. Machine model: a 200 pF cap is charged to the specified voltage, then discharged directly between two pins of the device
with no external series resistor (internal resistor < 5 Ω), done for all couples of pin combinations with other pins floating.
5. Human body model: 100 pF discharged through a 1.5 kΩ resistor between two pins of the device, done for all couples of pin
combinations with other pins floating.
