LTM2881CY-3#PBF

Overview

The LTM2881CY-3#PBF is a complete isolated RS-422/RS-485 transceiver module in a 32-pin BGA package. It integrates a half-duplex transceiver with an isolated DC/DC converter. The device operates on a 3V to 3.6V supply and supports data rates up to 20 Mb/s. It features a 2500 Vrms isolation rating via magnetic coupling. The module includes integrated ESD protection and fault protection for robust industrial communication.

Feature Summary

• Integrates isolated RS-422/RS-485 transceiver and power conversion in a single compact module
• Provides high-voltage galvanic isolation between system ground and bus lines
• Includes built-in electromagnetic interference filtering capabilities
• Offers comprehensive protection against electrostatic discharge and bus faults

Applications

• Industrial automation control systems
• Factory floor sensor networks
• Building management interfaces
• Medical equipment communication links

Procurement Notes

Verify the specific suffix #PBF confirms lead-free compliance and RoHS status before integration. Confirm the CY variant matches the required temperature range and package tolerance. Ensure the design accounts for the specific pinout of the 32-pin BGA format. Validate that the 3V input voltage aligns with the target system power rails.

Selection Notes

Select this component when space constraints require a fully integrated isolated interface solution. It is suitable for designs needing high-speed RS-485/RS-422 communication without external magnetics. Consider the thermal performance of the BGA package for enclosed enclosures. Evaluate the need for the specific 3V operating voltage range versus other variants.

Part Context

This part belongs to the LTM2881 series of uModule isolators from Analog Devices. These modules replace traditional discrete isolation components with integrated solutions. The series targets applications requiring reliable serial communication across galvanic barriers in noisy environments.
