LTM2882IY-5#PBF

Overview

The LTM2882IY-5#PBF is a complete galvanically isolated dual RS-232 μModule transceiver manufactured by Analog Devices Inc. It integrates two drivers and two receivers within a BGA-32 package, supporting data rates up to 10 Mb/s with half-duplex communication. The device operates on a single 4.5 V to 5.5 V supply, drawing 17 mA of quiescent current. It provides 2500 VRMS isolation and includes an integrated power module, eliminating the need for external components. Key electrical specifications include a maximum output current of 200 mA, propagation delay of 0.2 µs, and ESD protection rated at 10 kV.

Feature Summary

• Integrates dual RS-232 transceivers and power management in a single compact module
• Provides galvanic isolation without requiring external discrete components
• Features high common-mode transient immunity for reliable signal transmission

Applications

• Industrial communication systems requiring isolated serial interfaces
• Medical equipment needing safe patient connection isolation
• GPS navigation units with isolated data ports

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific suffix matches the required temperature grade and packaging format. Check for moisture sensitivity labeling and ensure proper handling procedures are followed during storage and assembly to maintain reliability standards.

Selection Notes

Select this component when a compact, fully integrated solution for dual isolated RS-232 links is required. It is suitable for designs where board space is limited and external isolation barriers or separate power supplies are undesirable. Ensure the application voltage range aligns with the 4.5 V to 5.5 V specification and that the thermal performance supports the operating environment.

Part Context

This part belongs to the LTM2882 series of μModule transceivers designed for robust serial communication. It serves as a specialized interface solution within Analog Devices' portfolio of isolation products, targeting applications that demand high reliability and minimal external circuitry complexity for serial data exchange.

Replacement Considerations

The LTM2882CY-5#PBF is a verified alternative within the same series, differing primarily in the commercial versus industrial temperature rating designation.
