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

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

). This is done for all couples of connected pin combinations

while the other pins are floating.
