These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam

during storage or handling to prevent electrostatic damage to the MOS gates.

(1)

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. Operation of the device beyond the Operating Ratings is not

recommended.

(2)

All voltages are measured with respect to AGND = DGND = 0V, unless otherwise specified.

(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 25 mA. The 50 mA maximum package input current rating limits the number of pins that can simultaneously safely exceed the

power supplies with an input current of 25 mA to two.

(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. The values for maximum power dissipation

listed above will be reached only when the device is operated in a severe fault condition (e.g. when input or output pins are driven

beyond the power supply voltages, or the power supply polarity is reversed). Such conditions should always be avoided.

(6)

Human body model is 100 pF capacitor discharged through a 1.5 k

Ω resistor. Machine model is 220 pF discharged through 0Ω.

(7)

Reflow temperature profiles are different for lead-free and non-lead-free packages.
