CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product reliability and

result in failures not covered by warranty.

NOTE:

1.

θJA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.

DC Operating Characteristics - RTC

Test Conditions: VDD = +2.7 to +5.5V, TA = -40°C to +85°C, unless otherwise stated.
