Maximum ratings
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.
Table 6.

Caution:
Negative undershoots below –0.3 V are not allowed on any pin while in the battery backup
mode.
Caution:
Do NOT wave solder SOIC to avoid damaging SNAPHAT sockets.

1.
For DIP package, 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.
3.
For SOH28 package, lead-free (Pb-free) lead finish: reflow at peak temperature of 260°C (the time above
255°C must not exceed 30 seconds).
