1. Input voltage is the voltage should be allowed to apply to the input terminal independent of the magnitude of VCC

+

The normal amplifier operation input voltage is within “Common Mode Input Voltage Range” specified in the Electrical characteristics.

2. This input current only exists when the voltage at any of the input leads is driven negative. It is due to the collector-vase junction of

the input PNP transistor becoming forward-biased and thereby acting as input diode clamp. In addition to this diode action, there is NPN parasitic

action on the IC chip. This transistor action can cause the output voltages of the Op-amps to go to the VCC voltage level (or to ground for

a large overdrive) for the time during which an input is driven negative.

3. Short-circuit can cause excessive heating and destructive dissipation. Values are typical.
