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

operation of the device is intended to be functional. For guaranteed specifications and test conditions, see the Electrical Characteristics.

(2)

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

specifications.

(3)

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

Ω resistor into each pin. Test method is per JESD-22-114.

(1)

Min and Max limits are 100% production tested at 25°C. Limits over the operating temperature range are guaranteed through correlation

using Statistical Quality Control (SQC) methods. Limits are used to calculate Average Outgoing Quality Level (AOQL).

(2)

Typical numbers are at 25°C and represent the most likely parametric norm.
