(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) If Military/Aerospace specified devices are required, contact the Texas Instruments Sales Office/ Distributors for availability and specifications.
(3) The maximum power dissipation is a function of TJ(MAX), RθJA. The maximum allowable power dissipation at any ambient temperature is PD = (TJ(MAX) – TA)/RθJA. All numbers apply for packages soldered directly into a PC board.

(1) 2.7-V and 4.5-V DC and AC Electrical Characteristics values apply only for factory testing conditions at the temperature indicated. Factory testing conditions result in very limited self-heating of the device such that TJ = TA. Parametric performance is not ensured in the 2.7-V and 4.5-V DC and AC Electrical Characteristics under conditions of internal self-heating where TJ > TA.
(2) All limits are specified by test or statistical analysis.
(3) Typical values represent the most likely parametric norm as determined at the time of characterization. Actual typical values may vary over time and depend on the application and configuration. The typical values are not tested and are not specified on shipped production material.
(4) This parameter is specified by design and/or characterization and is not tested in production.
(5) All limits are specified by design and measurements which are performed on a limited number of samples. Limits represent the mean ±3–sigma values. The typical value represents the statistical mean value.
