1. Short-circuits from the output to VCC + can cause excessive heating and potential destruction. The maximum output current

is approximately 20 mA, independent of the magnitude of VCC +

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 an input diode clamp. 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 during which an input is driven negative.

This is not destructive and normal output is restored for input voltages higher than -0.3 V.

3. Rthja/c are typical values.

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.
