Product Overview

The LTC1535ISW#PBF is an isolated RS485 full-duplex differential Line Transceiver 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 420kHz push-pull converter to power the isolated RS485 transceiver. Internal full-duplex communication occurs through the capacitive isolation barrier. The driver and receiver feature three-state outputs with the driver maintaining high impedance over the entire common mode range. The drivers have short-circuit current limits in both directions and a slow slew rate select to minimize EMI or reflections. The 68kR receiver input allows up to 128 node connections. A fail-safe feature defaults to a high output state when the receiver inputs are open or shorted.
  • failsafe output high for open or shorted receiver inputs
  • Short-circuit current limit
  • Slow slew rate control
  • Thermal shutdown
  • Eliminates ground loops
  • 250kBd Maximum data rate
  • 8kV ESD Protection on driver outputs and receiver inputs
