8582f
Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: The LT8582E is guaranteed to meet performance specifications
from 0°C to 125°C junction temperature. Specifications over the
–40°C to 125°C operating temperature range are assured by design,
characterization and correlation with statistical process controls. The
LT8582I is guaranteed over the full –40°C to 125°C operating junction
temperature range.

, unless otherwise noted (Note 2). Specifications
are identical for both channels unless noted otherwise.
Note 3: Current limit guaranteed by design and/or correlation to static test.
Note 4: This IC includes overtemperature protection that is intended
to protect the device during momentary overload conditions. Junction
temperature will exceed 125°C when overtemperature protection is active.
Continuous operation over the specified maximum operating junction
temperature may impair device reliability.
Note 5: Do not apply a positive or negative voltage or current source to
CLKOUT, otherwise permanent damage may occur.
