Output Short-circuit Duration 2)

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 VCC. Destructive dissipation can result from simultaneous short-circuit on all amplifiers.

Infinite

Iin

Input Current 3)

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 VCC 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.
