Solutions Interface RS485/RS422 Transceivers

DC241B - LTC1535CSW | Isolated RS485

Demonstration circuit 241B showcases the LTC®1535 isolated RS485 transceiver. The LTC1535 features 2,500V isolation; the “left-half” of the chip contains familiar RS485 logic functions and an isolated switching converter, and the “right-half” contains the RS485 transceiver. Both sides include a communications section to send data back and forth across the internal capacitive isolation barrier.
