1. Short-circuits from the output to VCC can cause excessive heating if VCC > 15V. The maximum output current is approximately 40mA independent  of the magnitude of V_CC. Destructive dissipation can result from simultaneous short-circuit on all amplifiers.
2. This input current only exists when the voltage at any of the input leads is driven negative. It is due to the collector-base junction of the input PNP transistor becoming forward biased and thereby acting as input diodes clamps. In addition to this diode action, there is also NPN parasitic action  on the IC chip. this transistor action can cause the output voltages of the Op-amps to go to the V_CC voltage level (or to ground for a large overdrive) for the time duration than an input is driven negative.
This is not destructive and normal output will set up again for input voltage higher than -0.3V.

These circuits LM158W,AW consist of two independent, high gain, internally frequency compensated which were designed specifically to operate from a sin-gle power supply over a wide range of voltages.The low power supply drain is independent of the magnitude of the power supply voltage. 

Application areas include transducer amplifiers,dc gain blocks and all the conventional op-amp circuits which now can be more easily implement-ed in single power supply systems. For example,these circuits LM158W,AW can be directly supplied with the standard +5V which is used in logic systems and will easily provide the required interface electron-ics without requiring any additional power supply.

Inthe linear mode the input common-mode voltage range includes ground and the output voltage can also swing to ground, even though operated from only a single power supply voltage.
