Either or both input voltages must not exceed the magnitude of VCC + or VCC-. 2. Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous short-circuits on all amplifiers. 3. Rth are typical values. 4. 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. 5. 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. 6. Charged device model: all pins plus package are charged together to the specified voltage and then discharged directly to ground. Table 2.
