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

diode clamps. In addition to this diode action, there is also NPN parasitic action on the IC chip. This

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

This is not destructive and normal output will set up again for input voltage higher than -0.3 V.

Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous short-

circuits on all amplifiers. These are typical values given for a single layer board (except for TSSOP which is

a two-layer board).
