MAXIMUM RATING
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 indicat-
ed in the Operating sections of this specification is
not implied. Exposure to Absolute Maximum Rat-
ing conditions for extended periods may affect de-
vice
reliability.
Refer
STMicroelectronics SURE Program and other rel-
evant quality documents.

Table 2. Absolute Maximum Ratings
Note: 1. Reflow at peak temperature of 215°C to 225°C for < 60 seconds (total thermal budget not to exceed 180°C for between 90 to 120
seconds).
CAUTION:
Negative undershoots below –0.3V are not allowed on any pin while in the Battery Back-up mode.
CAUTION:
Do NOT wave solder SOIC to avoid damaging SNAPHAT sockets.
