Note 1: All units are 100% production tested at TA = +25°C. Limits over the operating temperature range and relevant supply

voltage are guaranteed by design and characterization.

Note 2: The device is designed for continuous operation up to TJ = +125°C for 95000 hours and TJ = +150°C for 5000 hours.

Note 3: Guaranteed by design; not production tested.
