Working Principles

The LTC2873CUFD#TRPBF operates as an RS485/RS422 transceiver by converting the logic levels of incoming and outgoing signals between a microcontroller or other digital device and the RS485/RS422 bus. It uses differential signaling to transmit data, which provides noise immunity and allows for long-distance communication.

The transceiver's driver section converts the logic-level signals from the microcontroller into differential voltages suitable for transmission over the bus. The receiver section receives the differential signals from the bus and converts them back into logic-level signals for the microcontroller to process.
