(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 maximum Operating

Ratings is not recommended.

(2)

All voltages are measured with respect to GND = 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 at any pin exceeds 5.5V or is less than GND, the current at that pin should be limited per the Absolute Maximum

Ratings. The maximum package input current rating limits the number of pins that can safely exceed the power supplies.

(5)

The absolute maximum junction temperature (TJmax) for this device is 150°C. The maximum allowable power dissipation is dictated by

TJmax, the junction-to-ambient thermal resistance (θJA), and the ambient temperature (TA), and can be calculated using the formula

PDMAX = (TJmax − TA) / θJA. The values for maximum power dissipation 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 operating ratings, or the power supply polarity is reversed).

(6)

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

Ω resistor. Machine model is a 220 pF capacitor discharged

through 0

Ω. Charged device model simulates a pin slowly acquiring charge (such as from a device sliding down the feeder in an

automated assembler) then rapidly being discharged.
