Notes
a. Device mounted with all leads soldered or welded to multi-layer (1S2P)
JEDEC board, horizontal orientation.
b. Derate 5.5 mW/_C above T_A = 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.
