*6 The input common mode voltage or either input signal voltage should not be allowed to go negative by more than 0.3 V.
The upper end of the common mode voltage range is VCC -1.7 V.
*7 Short circuits from the output to VCC can cause excessive heating and eventual destruction.
Destructive dissipation can result from simultaneous shorts on all amplifiers.
