(1)
Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended
Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2)
All voltages are measured with respect to GND = 0 V, unless otherwise specified.
(3)
If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and
specifications.
(4)
When the input voltage at any pin exceeds 5.5 V or is less than GND, the current at that pin must be limited to 10 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 10
mA to two.
(5)
The absolute maximum junction temperature (TJmax) for this device is 150°C. The maximum allowable power dissipation is dictated by
TJmax, the junction-to-ambient thermal resistance (θJA), and the ambient temperature (TA), and can be calculated using the formula
PDMAX = (TJmax − TA) / θJA. The values for maximum power dissipation is reached only when the device is operated in a severe fault
condition (that is, when input or output pins are driven beyond the operating ratings, or the power supply polarity is reversed).

All voltages are measured with respect to GND = 0 V, unless otherwise specified.
(2)
The inputs are protected as shown below. Input voltage magnitudes up to 5.5 V, regardless of VA, do not cause errors in the conversion
result. For example, if VA is 3 V, the digital input pins can be driven with a 5-V logic device.
