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 100-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 to remove moisture prior

to soldering. Sipex ships the 100-pin LQFP in Dry Vapor

Barrier Bags with a humidity indicator card and desiccant pack.

The humidity indicator should be below 30%RH.
