(1) All voltages are measured with respect to GND = DR GND = 0V, unless otherwise specified.
(2) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. There is no ensurance of operation at the
Absolute Maximum Ratings. Operating Ratings indicate conditions for which the device is functional, but do not ensure specific
performance limits. For specifications and test conditions, see the Electrical Characteristics. The specified 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) When the input voltage at any pin exceeds the power supply limits (that is, less than GND or greater than V_A), the current at that pin
should be limited to 25 mA. The 50 mA maximum package input current rating limits the number of pins that can safely exceed the
power supplies with an input current of 25 mA to two. This limit is not placed upon the power, ground and digital output pins.
(4) Human body model is 100 pF capacitor discharged through a 1.5 kΩ resistor. Machine model is 220 pF discharged through ZERO
Ohms.
(5) See http://www.ti.com for methods of soldering surface mount devices.
