LTM2885IY#PBF

Overview

The LTM2885IY#PBF is a complete, galvanically isolated full-duplex RS-485/RS-422 micro-module transceiver manufactured by Analog Devices Inc. It integrates the transceiver and power supply into a single BGA-42 package. The device supports data rates up to 20 Mb/s with a common-mode transient immunity of 50 kV/µs. It operates within an industrial temperature range of -40°C to +85°C and provides 6500 VRMS isolation voltage.

Feature Summary

• Integrates isolated RS-485/RS-422 transceiver and power supply in a compact module
• Provides high common-mode transient immunity for noisy environments
• Supports full-duplex communication with integrated isolation barrier

Applications

• Industrial automation control systems
• Factory floor sensor networks
• Building automation interfaces

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific suffix matches the required isolation rating and package variant. Check current availability status as supply may be limited. Ensure ESD handling protocols are followed during storage and installation due to moisture sensitivity classification.

Selection Notes

Select this component when designing systems requiring robust galvanic isolation between microcontrollers and RS-485/RS-422 buses. It is suitable for applications demanding high noise immunity and simplified PCB layout. Consider the BGA-42 footprint constraints and thermal management requirements during the design phase.

Part Context

This part belongs to the LTM2881/LTM2885 family of μModule transceivers. These devices consolidate complex isolated power and signal paths into a single surface-mount package. They eliminate the need for discrete isolation components, reducing board space and design complexity for industrial communication interfaces.

Replacement Considerations

LTM2881IY#PBF is a confirmed substitute within the same family offering similar isolated RS-485/RS-422 functionality.
