(1) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and
specifications.
(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) All voltages are measured with respect to GND, unless otherwise specified.
(4) The Absolute maximum input range for :
(a) +2.5Vin - −0.3V to (1.4 x V+ + 0.42V or 6V, whichever is smaller
(b) +3.3Vin - −0.3V to (1.8 x V+ + 0.55V or 6V, whichever is smaller.
(5) The human body model is a 100 pF capacitor discharged through a 1.5 kΩ resistor into each pin. The machine model is a 200 pF
capacitor discharged directly into each pin.
(6) See www.ti.com for other methods of soldering surface mount devices.
