CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
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, Temperature = -20°C to +70°C, unless otherwise stated.
