ABSOLUTE MAXIMUM RATINGS
These are stress ratings only and functional operation
of the device at these ratings or any other above those
indicated in the operation sections of the specifications
below is not implied. Exposure to absolute maximum
rating conditions for extended periods of time may
affect reliability.

STORAGE CONSIDERATIONS
Due to the relatively large package size of the 80-pin
quad flat-pack, storage in a low humidity environment
is preferred. Large high density plastic packages
are moisture sensitive and should be stored in Dry
Vapor Barrier Bags. Prior to usage, the parts should
remain bagged and stored below 40°C and 60%RH.
If the parts are removed from the bag, they should be
used within 48 hours or stored in an environment at
or below 20%RH. If the above conditions cannot be
followed, the parts should be baked for four hours at
125°C in order remove moisture prior to soldering.
Exar ships the 80-pin QFP in Dry Vapor Barrier Bags
with a humidity indicator card and desiccant pack.The
humidity indicator should be below 30%RH.
