(1)

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings

only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended

Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

Soldering process must comply with Reflow Temperature Profile specifications. Refer to www.ti.com/packaging.

(1)

The Human Body Model (HBM) is a 100-pF capacitor charged to the specified voltage then discharged through a 1.5-k

Ω resistor into

each pin. The Machine Model (MM) is a 200 pF capacitor charged to the specified voltage then discharged directly into each pin. The

Charged Device Model (CDM) is a specified circuit characterizing an ESD event that occurs when a device acquires charge through

some triboelectric (frictional) or electrostatic induction processes and then abruptly touches a grounded object or surface.

(2)

JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.

(3)

JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.
