LTM2881IV-3#PBF Description

Short technical summary and product information.

The Linear Technology LTM2881IV-3#PBF is a comprehensive µModule transceiver designed for isolated RS485 and RS422 communication. This device integrates a full-duplex transceiver with an isolated 5V DC/DC converter, eliminating the need for external components. It provides 2500VRMS of isolation, making it suitable for applications where breaking ground loops is essential and allowing for large common mode voltage variations.

 

Key electrical specifications include a maximum data rate of 20Mbps or a low EMI 250kbps mode. The transceiver offers enhanced ESD protection, withstanding up to ±15kV HBM on interface pins and ±10kV through the isolation barrier. It supports a wide logic supply range from 1.62V to 5.5V, ensuring compatibility with various logic levels. The integrated selectable 120Ω termination further simplifies design.

 

This transceiver is ideal for industrial networks, breaking RS485 ground loops, and isolated PROFIBUS-DP networks. It operates through significant common mode transients, guaranteeing uninterrupted communication. The device is available in BGA and LGA packages, measuring 15mm x 11.25mm, and is designed for surface mount applications.
