Notes:

a. Derate 20 mW/°C above 70 °C.

b. Device 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.

Notes:

a. Full = - 40 °C to 85 °C.

b. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum (- 40 °C to 85 °C).

c. Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.

d. Minimum Operating Voltage is determined by the battery’s capability to provide energy as it is deeply discharged.
