Either or both input voltages must not exceed the magnitude of VCC + or VCC-. 2. Short-circuits can cause excessive heating and destructive dissipation. 3. Rth are typical values. 4. Human body model: A 100 pF capacitor is charged to the specified voltage, then discharged through a 1.5 k resistor between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating. 5. 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 ). This is done for all couples of connected pin combinations while the other pins are floating. 6. Charged device model: all pins and the package are charged together to the specified voltage and then discharged directly to ground through only one pin. This is done for all pins. Table 2.

All models are a trade-off between accuracy and complexity (i.e. simulation time). Macromodels are not a substitute to breadboarding; rather, they confirm the validity of a design approach and help to select surrounding component values. A macromodel emulates the nominal performance of a typical device within specified operating conditions (temperature, supply voltage, for example). Thus the macromodel is often not as exhaustive as the datasheet, its purpose is to illustrate the main parameters of the product. Data derived from macromodels used outside of the specified conditions (VCC, temperature, for example) or even worse, outside of the device operating conditions (VCC, Vicm, for example), is not reliable in any way. Section 4.2 provides the electrical characteristics resulting from the use of this macromodel. 4.2 Electrical characteristics from macromodelization Table 4.
