2. Short-circuits from the output to V
CC
can cause excessive heating if V
CC
> 15 V. The maximum output
current is approximately 40 mA independent of the magnitude of V
CC
. Destructive dissipation can result
from simultaneous short-circuits on all amplifiers.

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
diode 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 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.

4. 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).

6. Machine model: a 200 pF cap is charged to the specified voltage, then discharged directly between two
pins of the device with no external series resistor (internal resistor < 5 Ω), done for all couples of pin
combinations with other pins floating.
