*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 sections of
this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may
affect reliability.
**Junction temperature depends upon package type,
cycle time, loading, ambient temperature and air-
flow. See Micron Technical Note TN-05-14 for more
information.
