(1)

All voltages are measured with respect to GND, unless otherwise specified.

(2)

Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for

which the device is functional, but do not ensure specific performance limits. For ensured specifications and test conditions, see the

Electrical Characteristics. The ensured specifications apply only for the test conditions listed. Some performance characteristics may

degrade when the device is not operated under the listed test conditions.

(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 (VIN) at any pin exceeds the power supplies (VIN < GND or VIN > VA+ or VD+), the current at that pin should be

limited to 30 mA. The 120 mA maximum package input current rating limits the number of pins that can safely exceed the power

supplies with an input current of 30 mA to four.

(5)

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 at any temperature is PD = (TJmax − TA)/θJA or the number given in the Absolute

Maximum Ratings, whichever is lower.

(6)

The human body model is a 100 pF capacitor discharged through a 1.5 k

Ω resistor into each pin.

(7)

See AN450 “Surface Mounting Methods and Their Effect on Product Reliability” or the section titled “Surface Mount” found in any post

1986 Linear Data Book for other methods of soldering surface mount devices.
