(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.

(2)

All voltage values are with respect to the local ground pin (GND1 or GND2) and are peak voltage values.

(1)

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

(2)

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

(3)

IEC ESD strike is applied across the barrier with all pins on each side tied together creating a two-terminal device.

(4)

Testing is carried out in air or oil to determine the intrinsic contact discharge capability of the device.
