Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 4:
This device includes over-temperature protection that is intended may cause permanent damage to the device. Exposure to any Absolute to protect the device during momentary overload conditions. Junction Maximum Rating condition for extended periods may affect device temperature will exceed 125°C when overtemperature protection is active. reliability and lifetime. Continuous operation above specified maximum operating junction
Note 2:
Guaranteed by design and not subject to production test. temperature may result in device degradation or failure.
Note 3:
Maximum Data Rate is guaranteed by other measured parameters
Note 5:
Tests performed from GND to GND2, all pins shorted each side of and is not tested directly. isolation barrier.
Note 6:
The rated dielectric insulation voltage should not be interpreted as a continuous voltage rating. 2882fh For more information www.linear.com/LTM2882 5 Document Outline FEATURES DESCRIPTION APPLICATIONS TYPICAL APPLICATION ABSOLUTE MAXIMUM RATINGS PIN CONFIGURATION ORDER INFORMATION ELECTRICAL CHARACTERISTICS SWITCHING CHARACTERISTICS ISOLATION CHARACTERISTICS TYPICAL PERFORMANCE CHARACTERISTICS TEST CIRCUITS PIN FUNCTIONS BLOCK DIAGRAM APPLICATIONS INFORMATION TYPICAL APPLICATIONS PACKAGE DESCRIPTION REVISION HISTORY TYPICAL APPLICATIONS RELATED PARTS
