1. Caution: this device is not protected in the event of abnormal operating conditions such as short-circuiting
between any one output pin and ground or between any one output pin and V_CC, and between individual
output pins.
2. All voltage values are measured with respect to the ground pin.
3. The magnitude of the input signal must never exceed V_CC + 0.3 V/GND - 0.3 V.
4. Exceeding the power derating curves during a long period will provoke abnormal operation.
5. Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a
1.5 kΩ resistor between two pins of the device. This is done for all couples of connected pin combinations
while the other pins are floating.
6. 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.
7. 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 is done for all pins.
8. The magnitude of the standby signal must never exceed V_CC + 0.3 V/GND - 0.3 V.
