LTM2881 fullduplex RS485/RS422

Linear Technology introduces the LTM2881 complete galvanically isolated fullduplex RS485/RS422 μModuleR transceiver. LTM2881 required no external components .

LTM2881 device is ideal for systems where themground loop is broken allowing for large common mode voltage variation. Maximum data rates are 20Mbps or 250kbps in slew limited mode.

A logic supply pin allows easy interfacing with different logic levels from 1.62V to 5.5V.

Other features of the LTM2881 transceiver are : Isolated RS485/RS422 Transceiver: 2500VRMS , Integrated Isolated DC/DC Converter: 1W, 62% Efficiency , No External Components Required , 20Mbps or Low EMI 250kbps Data Rate , High ESD: ±15kV HBM on Transceiver Interface , High Common Mode Transient Immunity: 30kV/μs , Integrated Selectable 120Ω Termination , 3.3V (LTM2881-3) or 5.0V (LTM2881-5) Operation , 1.62V to 5.5V Logic Supply Pin for Flexible Digital Interface , Common Mode Working Voltage: 560VPEAK ,Current Limited Drivers and Thermal Shutdown , Compatible with TIA/EIA-485-A Specification .
