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. Unless otherwise noted, all voltages are referenced
to GND.

Note:
1. Junction-to-ambient thermal resistance, ΘJA, is a strong function of PCB material, board thickness, thickness
and number of copper planes, number of via used, diameter of via used, available copper surface, and attached
heat sink characteristics. It is measured with the device mounted on a board of FR-4 material, 0.063inch
thickness, no copper plane, and zero air flow.
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.
