DESCRIPTION
The LTM®2882 is a complete galvanically isolated dual RS232 µModule®(micromodule)transceiver. 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.
