(1)
Absolute Maximum Ratings indicate limits beyond which damage to the component may occur. Operating Ratings are conditions under
which operation of the device is ensured. Operating Ratings do not imply specified performance limits. For specified performance limits
and associated test conditions, see the Electrical Characteristics table.
(2)
All voltages are with respect to the potential at the GND pins.
(3)
If Military/Aerospace specified devices are required, please contact the TI Sales Office/ Distributors for availability and specifications.
(4)
Internal thermal shutdown circuitry protects the device from permanent damage. Thermal shutdown engages at TJ = 150°C (typ.) and
disengages at TJ = 130°C (typ.).
(5)
The Human body model is a 100 pF capacitor discharged through a 1.5 k
Ω resistor into each pin. (MIL-STD-883 3015.7) The machine
model is a 200 pF capacitor discharged directly into each pin. TI recommends that all integrated circuits be handled with Appropriate
precautions. Failure to observe proper ESD handling techniques can result in damage.

Absolute Maximum Ratings indicate limits beyond which damage to the component may occur. Operating Ratings are conditions under
which operation of the device is ensured. Operating Ratings do not imply specified performance limits. For specified performance limits
and associated test conditions, see the Electrical Characteristics table.
(2)
All voltages are with respect to the potential at the GND pins.
(3)
In applications where high power dissipation and/or poor package thermal resistance is present, the maximum ambient temperature may
have to be de-rated. Maximum ambient temperature (TA-MAX) is dependent on the maximum operating junction temperature (TJ-MAX-OP =
125°C), the maximum power dissipation of the device in the application (PD-MAX), and the junction-to ambient thermal resistance of the
part/package in the application (
θJA), as given by the following equation: TA-MAX = TJ-MAX-OP – (θJA × PD-MAX).

(1)
Junction-to-ambient thermal resistance (
θJA) is taken from thermal measurements, performed under the conditions and guidelines set
forth in the JEDEC standard JESD51-7. A 1" x 1", 4 layer, 1.5 oz. Cu board was used for the measurements.
