LTM2881MPY-5#PBF

LTM2881MPY-5#PBF is a complete galvanically isolated full-duplex RS485/RS422 µModule® (micromodule) transceiver + power. No external components are required. A single supply powers both sides of the interface through an integrated, isolated, low noise, efficient 5V output DC/DC converter. Coupled inductors and an isolation power transformer provides 2500VRMS of isolation between the line transceiver and the logic interface. This device is ideal for systems where the ground loop is broken allowing for large common mode voltage variation. Uninterrupted communication is guaranteed for common mode transients greater than 30kV/μs. Transmit data, DI and receive data, RO, are implemented with event driven low jitter processing. The receiver has a one-eighth unit load supporting up to 256 nodes per bus. Application includes isolated RS485/RS422 interface, industrial networks, breaking RS485 ground loops, isolated PROFIBUS-DP networks.
