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) All voltages are measured with respect to GND, unless otherwise specified.
(2) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for
which the device is functional, but do not ensure specific performance limits. For ensured specifications and test conditions, see the
Electrical Characteristics. The ensured specifications apply only for the test conditions listed. Some performance characteristics may
degrade when the device is not operated under the listed test conditions.
(3) The Absolute maximum input range for: +2.5Vin - −0.3 V to (1.4 × V
+
+ 0.42 V or 6 V, whichever is smaller +3.3Vin - −0.3 V to (1.8 ×
V
+
+ 0.55 V or 6 V, whichever is smaller.
(4) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and
specifications.
(5) When the input voltage (V
IN
) at any pin exceeds the power supplies (V
IN
< GND or V
IN
>V
+
), the current at that pin should be limited to
5 mA. The 20 mA maximum package input current rating limits the number of pins that can safely exceed the power supplies with an
input current of 5 mA to four.
(6) The human body model is a 100 pF capacitor discharged through a 1.5 kΩ resistor into each pin.
