LTM2881HY-3#PBF - Isolated RS485/RS422 µModule Transceiver with Integrated Power

The LTM2881HY-3#PBF is a complete galvanically isolated RS485/RS422 transceiver from Linear Technology, designed to provide robust communication in noisy environments and across large ground differences. This product is part of Linear Technology's µModule (micro module) series, which encapsulates all the necessary components for isolated communication into a single, compact package. The LTM2881HY-3#PBF is ideal for industrial, instrumentation, and networking applications where reliable data transmission is critical.

Key Features:

• Integrated Isolation: The transceiver features onboard isolation, providing 2500Vrms for 1 minute per UL 1577. This ensures signal integrity and protects against high voltage spikes and ground loops.
• Integrated Power: It includes an isolated DC/DC converter to power the isolation barrier and the transceiver, simplifying the design and reducing external component count.
• Robust Data Transmission: Supports RS485 and RS422 communication standards, with a data rate up to 20Mbps, making it suitable for high-speed data acquisition and control applications.
• Enhanced ESD Protection: The device has enhanced ESD protection up to ±15kV (Human Body Model) on the transceiver interface pins, safeguarding the device from electrostatic discharges during handling and operation.
• Adjustable Cable Termination: The module provides an integrated selectable termination resistor, allowing for easy adaptation to the requirements of the communication bus.
• Cross Isolation Fault Protection: It is designed to withstand ±10V common mode transients, ensuring reliable operation even in the presence of electrical noise and transients.

Applications:

• Industrial Data Links
• Networked Devices in Harsh Environments
• Ground Loop Breaking
• Isolated Sensor Interfaces
• Isolated UART
