3 All voltage values, except differential voltage, are with respect to the zero reference level (ground) of the supply voltages where the zero reference level is the midpoint between VCC+ and The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 15 volts, whichever is Differential voltages are the non-inverting input terminal with respect to the inverting input Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous short-circuits on all Rth are typical The output may be shorted to ground or to either supply. Temperature and/or supply voltages must be limited to ensure that the dissipation rating is not Human body model: 100 pF discharged through a k resistor between two pins of the device, done for all couples of pin combinations with other pins floating.
