FEATURES  
DESCRIPTION  
6-Channel Logic Isolator: 2500V  
for 1 Minute  
The LTM®2887 is a complete galvanic digital µModule®  
(micromodule) isolator. No external components are  
required. A single 3.3V or 5V supply powers both sides  
of the interface through an integrated, isolated DC/DC  
converter. A logic supply pin allows easy interfacing with  
different logic levels from 1.62V to 5.5V, independent of  
the main supply.
