Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.

IV
Parameter is guaranteed by design and characterization
testing.
V Parameter is a typical value only.
VI
Devices are 100% production tested at 25°C and
guaranteed by design and characterization testing
for industrial operating temperature range.
