Soldering Information

See Applications Note AN-1112 (Literature Number SNVA009).

(1)

“Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur, including inoperability and degradation of

device reliability and/or performance. Functional operation of the device and/or non-degradation at the Absolute Maximum Ratings or

other conditions beyond those indicated in the Recommended Operating Conditions is not implied. The Recommended Operating

Conditions indicate conditions at which the device is functional and the device should not be operated beyond such conditions. All

voltages are measured with respect to the ground pin, unless otherwise specified.

(2)

The Electrical Characteristics tables list ensured specifications under the listed Recommended Operating Conditions except as

otherwise modified or specified by the Electrical Characteristics Conditions and/or Notes. Typical specifications are estimations only and

are not ensured.

(3)

If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and

specifications.

(4)

The maximum power dissipation must be derated at elevated temperatures and is dictated by TJMAX, θJA, and the ambient temperature,

TA. The maximum allowable power dissipation is PDMAX = (TJMAX - TA) / θJA or the number given in Absolute Maximum Ratings,

whichever is lower.
