Notes:
a. Device mounted with all leads soldered or welded to PC board.
b. Derate 7.2 mW/°C above 25 °C.
* Exposure to Absolute Maximum rating conditions for extended periods may affect device reliability. Stresses above Absolute Maximum rating
may cause permanent damage. Functional operation at conditions other than the operating conditions specified is not implied. Only one
Absolute Maximum rating should be applied at any one time.
