All values, except differential voltage are with respect to network terminal. 2. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal. 3. The magnitude of input and output terminal must never exceed VCC + 0.3 V. 4. Short-circuits can cause excessive heating and destructive dissipation. 5. Rth are typical values. 6. Human body model: 100 pF discharged through a 1.5 k resistor between two pins of the device, done for all couples of pin combinations with other pins floating. Table 2.
