Notes

Device mounted with all leads soldered or welded to multi-layer (1S2P)

JEDEC board, horizontal orientation.

Derate 5.5 mW/_C above TA = 25_C.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation

of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating

conditions for extended periods may affect device reliability.
