Working Principles

The LTC1687IS#TRPBF operates as a transceiver by converting the electrical signals between RS485/RS422 protocols and the internal logic levels of connected devices. It uses differential signaling to transmit and receive data, allowing for noise immunity and long-distance communication.

When transmitting, the driver inputs (DI, A, B) receive digital signals and convert them into differential voltages on the driver outputs (Y, Z). On the receiving end, the receiver inputs (A, B) detect the differential voltages and convert them back into digital signals on the receiver output (RO).

The DE and RE pins control the enable/disable states of the driver and receiver, respectively, allowing for half-duplex communication.
