Applications
The LTM2881MPY-3 is designed for isolated RS-485 and RS-422 communication links in industrial automation, PLCs, and motor-drive systems where ground-potential differences can damage conventional transceivers. Its integrated isolated power supply removes the need for a separate isolated DC-DC converter, simplifying board layout on 2-wire or 4-wire fieldbus networks. The device is also well suited for process instrumentation and medical equipment requiring reliable data isolation up to 2500 V RMS.

Frequently Asked Questions
What maximum data rate does the LTM2881MPY-3 support on an RS-485 bus?
The LTM2881MPY-3 supports data rates up to 20 Mbps on both RS-485 and RS-422 buses, making it appropriate for high-speed industrial fieldbus links where deterministic latency and bandwidth across 2-wire or 4-wire differential networks are essential requirements.
How much isolation voltage does the LTM2881MPY-3 provide, and why does that matter for motor-drive wiring?
The LTM2881MPY-3 provides 2500 V RMS galvanic isolation between its logic side and bus side. In motor-drive installations, ground potential differences of hundreds of volts between a control cabinet and a drive chassis are common, and this isolation level prevents those transients from damaging the host microcontroller or PLC.
Does the LTM2881MPY-3 include an isolated power supply, and what supply voltage does it require?
Yes, the LTM2881MPY-3 integrates a complete isolated DC-DC converter, so no external isolated supply is needed. It operates from a single 3.3 V or 5 V supply on the logic side and generates its own isolated bus-side power, significantly reducing BOM count and board area in isolated RS-485 designs.
