Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 4:
This µModule transceiver includes overtemperature protection that may cause permanent damage to the device. Exposure to any Absolute is intended to protect the device during momentary overload conditions. Maximum Rating condition for extended periods may affect device Junction temperature will exceed 125°C when overtemperature protection reliability and lifetime. is active. Continuous operation above specified maximum operating
Note 2:
Guaranteed by design and not subject to production test. junction temperature may result in device degradation or failure.
Note 3:
Maximum Data rate is guaranteed by other measured parameters
Note 5:
Device considered a 2-terminal device. Pin group A1 through B8 and is not tested directly. shorted together and pin group K1 through L8 shorted together.
Note 6:
The rated dielectric insulation voltage should not be interpreted as a continuous voltage rating. 2881fi 6 For more information www.linear.com/LTM2881 Document Outline Features Applications Typical Application Description Absolute Maximum Ratings Pin Configuration Order Information Electrical Characteristics Switching Characteristics Isolation Characteristics Typical Performance Characteristics Pin Functions Block Diagram Test Circuits Functional Table Applications Information Typical Applications Package Description Revision History Typical Application Related Parts
