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. Sipex 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.
