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 LT1942 is guaranteed to meet performance specifications
from 0 ° C to 70 ° C. Specifications over the –40 ° C to 85 ° C operating
temperature range are assured by design, characterization and correlation
with statistical controls.
Note 3: Current flows out of the pin.
Note 4: Current limit guaranteed by design and/or correlation to static test.
Note 5: V CESAT 100% tested at wafer level.
