Differential voltages are the non-inverting input terminal with respect to the inverting input terminal. The magnitude of input and output voltages must never exceed VCC+ +0.3V. Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous short-circuit on all amplifiers.
