2. Short-circuits can cause excessive heating and destructive dissipation. Values are typical.

3. 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.

4. 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.

5. 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.

1. The input common-mode voltage of either input signal voltage should not be allowed to go negative by

more than 0.3 V. The upper end of the common-mode voltage range is VCC+ –1.5 V, but either or both

inputs can go to +30 V without damage.
