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 VCC, and between individual

output pins.

2. All voltage values are measured with respect to the ground pin.

Input voltage (3)

3. The magnitude of the input signal must never exceed VCC + 0.3 V/GND - 0.3 V.

4. Exceeding the power derating curves during a long period will provoke abnormal operation.

ESD

Human body model(5)

5. 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.

Machine model(6)

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.

Charged device model(7)

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.
