All voltage values, except differential voltage are with respect to network ground terminal. 2. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal. 3. Short-circuits from the output to VCC can cause excessive heating if VCC + > 15 V. The maximum output current is approximately 40 mA, independent of the magnitude of VCC. Destructive dissipation can result from simultaneous short- circuits on all amplifiers. 4. 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 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 above -0.3 V. 5. Short-circuits can cause excessive heating and destructive dissipation. Rth are typical values. 6. Human body model: 100 pF discharged through a 1.5 k Ω resistor between two pins of the device, done for all couples of pin combinations with other pins floating. 7. 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. 8. Charged device model: all pins plus package are charged together to the specified voltage and then discharged directly to the ground. Table 2.
