LT LTM2881IY-5#PBF

Магнитная муфта22500 Вrms

Overview

The LTM2881IY-3#PBF is a complete galvanically isolated full-duplex RS485/RS422 µModule® Transceiver with a single supply it 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 provide 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. Maximum data rates are 20Mbps or 250kbps in slew limited mode. 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. A logic supply pin allows easy interfacing with different logic levels from 3 to 3.6V, independent of the main supply.
