SiP12506

Notes:

a. The human body model is a 100 pF capacitor discharged through a 1.5 k

Ω resistor into each pin.

b. Derate 20 mW/°C above 70 °C.

c. Devise mounted with all leads soldered or welded to PC board.

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.
