Working Principles

LTC1347CG#TRPBF works based on the RS485/RS422 standard. It uses differential signaling to transmit data over long distances while maintaining noise immunity. The driver section converts the logic-level signals into balanced differential voltages, which are then transmitted over the bus. The receiver section detects these differential voltages and converts them back into logic-level signals.
