Stressing the device above the rating listed in the absolute maximum ratings table may

cause permanent damage to the device. These are stress ratings only and operation of the

device at these or any other conditions above those indicated in the operating sections of

this specification is not implied. Exposure to absolute maximum rating conditions for

extended periods may affect device reliability.

1. Soldering temperature of the IC leads is to not exceed 260 °C for 10 seconds. In order to protect the lithium

battery, preheat temperatures must be limited such that the battery temperature does not exceed +85 °C.

Furthermore, the devices shall not be exposed to IR reflow.

2. For DIP packaged devices, ultrasonic vibrations should not be used for post-solder cleaning to avoid

damaging the crystal.

Caution: Negative undershoots below –0.3 volts are not allowed on any pin while in the battery

backup mode.
