(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) For soldering specifications see product folder at http://www.ti.com and http://www.ti.com/lit/SNOA549
(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 (VIN) exceeds the power supply (VIN < GND or VIN > VA), the current at that pin must be limited to 5mA and
VIN has to be within the Absolute Maximum Rating for that pin. The 20 mA package input current rating limits the number of pins that
can safely exceed the power supplies with current flow to four pins.
