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 44-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. Sipex ships
the 44-pin QFP in Dry Vapor Barrier Bags with
a humidity indicator card and desiccant pack. The
humidity indicator should be below 30%RH.
