These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for
which the device is intended to be functional, but specific performance is not ensured. For ensured specifications and the test
conditions, see the Electrical Characteristics.
(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
+
voltage 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
+
can cause excessive heating and eventual destruction. When considering short circuits to ground the
maximum output current is approximately 40mA independent of the magnitude of V
+
. At values of supply voltage in excess of +15V,
continuous short circuits can exceed the power dissipation ratings and cause eventual destruction.
