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 LT3741E is guaranteed to meet performance specifications
from 0°C to 125°C junction temperature. Specifications over the –40°C
to 125°C operating junction temperature range are assured by design,
characterization and correlation with statistical process controls. The
LT3741I is guaranteed to meet performance specifications over the –40°C
to 125°C operating junction temperature range.
Note 3: The minimum on, off, and nonoverlap times are guaranteed by
design and are not tested.
