(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for
which the device is intended to be functional. For specifications and test conditions, see the Electrical Characteristics. The specifications
apply only for the test conditions listed.
(2) Refer to RETS185H for military specifications.
(3) If Military/Aerospace specified devices are required, please contact the TI Sales Office/Distributors for availability and specifications.
(4) For elevated temperature operation, see Table 1 and Thermal Characteristics.
(5) The human body model is a 100 pF capacitor discharged through a 1.5 kΩ resistor into each pin.
