Notes: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.

Absolute maximum ratings are stress ratings only and functional device operation is not implied.

2. This input current will only exist when the voltage at any of the input leads is driven negative. It is due to

the collector base junction of the input PNP transistors becoming forward biased and thereby acting as

input diode clamps. In addition to this diode action, there is also lateral NPN parasitic transistor action on

the IC chip. This transistor action can cause the output voltages of the op amps to go to the V

level (or to ground for a large overdrive) for the time duration that an input is driven negative. This is not

destructive and normal output states will re-establish when the input voltage, which was negative, again

returns to a value greater than -0.36V (at 25°C).

3. Short circuits from the output V

short circuits to ground the maximum output current is approximately 40mA independent of the magnitude

of V

dissipation ratings and cause eventual destruction.
