Working Principles

The SN65HVD234DRG4 is an RS-485 transceiver that operates on a half-duplex communication protocol. It uses differential signaling to transmit and receive data over long distances. The driver section converts the logic-level signals into differential voltages, while the receiver section converts the differential voltages back into logic-level signals. The transceiver incorporates protection features such as short-circuit protection and thermal shutdown to ensure reliable operation in industrial environments.
