1. 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.
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 during which an input is driven
negative. This is not destructive and normal output is restored when the input voltage goes back above -0.3V.
3. Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous short-circuits on all
amplifiers. All values are typical.
4. Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a 1.5 kΩ resistor
between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating.
5. Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between two pins of the
device with no external series resistor (internal resistor < 5 Ω). This is done for all couples of connected pin combinations
while the other pins are floating.
6. Charged device model: all pins and the package are charged together to the specified voltage and then discharged directly
to the ground through only one pin. This is done for all pins. The CDM value applies to SO-8 only.
