Notes:
1. Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a
stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational
section of this specification is not implied. Exposure to the absolute maximum rating conditions for extended periods of time may
affect reliability.
2. Soldering temperature not to exceed 260
°
C for 10 seconds (total thermal budget not to exceed 150
°
C for longer than 30 seconds).
CAUTION:
Negative undershoots below –0.3 volts are not allowed on any pin while in the Battery Back-up mode.
CAUTION:
Do NOT wave solder SOIC to avoid damaging SNAPHAT sockets.
