Absolute Maximum Ratings

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be

operable above the recommended operating conditions and stressing the parts to these levels is not recommended.

In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.

The absolute maximum ratings are stress ratings only. TA=25°C, unless otherwise specified.

Notes:

2.

Mounted on 76.2 x 114.3 x 1.6 mm PCB (FR-4 glass epoxy material).

3.

Refer to the following standards:

JESD51-2: Integral circuits thermal test method environmental conditions - natural convection

JESD51-3: Low effective thermal conductivity test board for leaded surface-mount packages.

4.

Do not exceed PD under any circumstances.

Recommended Operating Conditions

The Recommended Operating Conditions table defines the conditions for actual device operation. Recommended

operating conditions are specified to ensure optimal performance to the datasheet specifications. Fairchild does not

recommend exceeding them or designing to Absolute Maximum Ratings.
