Absolute Maximum Ratings indicate limits beyond which damage to the component may occur. Operating Ratings are conditions under

which operation of the device is specified. Operating Ratings do not imply ensured performance limits. For specified performance limits

and associated test conditions, see the Electrical Characteristics tables.

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

specifications.

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.
