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 LT3756E and LT3756E-1 are 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 LT3756I and LT3756I-1 are guaranteed to meet performance

specifications over the –40°C to 125°C operating junction temperature

range.
