Working Principles

The LTC1696HS6#TRPBF operates as an interface between devices using the RS485/RS422 standard. It converts the single-ended signals from the driver input (DI) into differential signals on the RS485/RS422 differential data inputs (B, A). These differential signals are then transmitted over long distances, providing noise immunity and reducing signal degradation.

On the receiving end, the transceiver converts the differential signals received on the RS485/RS422 receiver output (RO) into single-ended signals. The driver enable (DE) and receiver enable (/RE) pins control the direction of data flow, allowing the transceiver to function as both a transmitter and a receiver.
