Product Summary
The LTC1535CSW#TRPBF is an isolated RS485 full-duplex differential line transceiver. Isolated RS485 is ideal for systems where the ground loop is broken to allow for much larger common mode voltage ranges. An internal capacitive isolation barrier provides 2500VRMS of isolation between the line transceiver and the logic level interface. The powered side contains a 400kHz push-pull converter to power the isolated RS485 transceiver. Internal full-duplex communication occurs through the capacitive isolation barrier. The transceiver meets RS485 and RS422 requirements. The applications of the LTC1535CSW#TRPBF include Isolated RS485 Receiver/Driver, RS485 with Large Common Mode Voltage, Breaking RS485 Ground Loops, Multiple Unterminated Line Taps.
