LTM2882HY-5#PBF

Overview

The LTM2882HY-5#PBF is a complete galvanically isolated dual RS-232 μModule transceiver manufactured by Analog Devices Inc. It integrates two independent, fully isolated RS-232 transceivers with integrated power supplies into a single LGA-32 package. The device supports data rates up to 1 Mb/s and operates on a single 4.5 V to 5.5 V supply. Key electrical parameters include a maximum operating temperature of +105°C, minimum operating temperature of -40°C, and an ESD protection rating of 10 kV. It features half-duplex communication with two drivers and two receivers.

Feature Summary

• Integrates dual isolated RS-232 transceivers with built-in power conversion, eliminating the need for external components.
• Provides galvanic isolation between logic and serial bus sides to protect sensitive electronics from high voltage transients.
• Supports high common-mode transient immunity for reliable operation in electrically noisy industrial environments.

Applications

• Industrial automation systems requiring isolated serial communication
• Medical equipment needing safety-isolated data links
• Test and measurement instruments with multiple isolated interfaces

Procurement Notes

Verify the specific suffix HY-5 against the official Analog Devices datasheet to confirm pinout and isolation ratings match your design requirements. Confirm RoHS compliance status through the manufacturer's current documentation. Check for moisture sensitivity level (MSL) handling requirements during storage and assembly. Ensure the LGA-32 package footprint aligns with your PCB layout constraints.

Selection Notes

Select this component when a compact solution for dual isolated RS-232 channels is required without external magnetics or capacitors. Consider the LGA-32 package size relative to available board space. Evaluate the 1 Mb/s data rate capability against system throughput needs. Verify that the 2500 VRMS isolation rating meets the safety standards of the target application environment.

Part Context

This part belongs to the LTM2882 series of μModule isolators. These devices combine analog and digital functions with magnetic coupling technology to provide robust isolation. The series is designed to simplify the design-in process for isolated communication interfaces by integrating passive components typically required for isolation barriers.

Replacement Considerations

Consult the Analog Devices product selector guide for compatible alternatives within the LTM2882 family. Verify if variants such as LTM2882CY-5#PBF offer identical functionality with different packaging or thermal characteristics. Ensure any substitute maintains the same isolation voltage and data rate specifications.
