LTM2882HY-3#PBF

Drivers, Receivers, Transceivers Overview

The LTM2882HY-3#PBF is a dual isolated RS232 µModule transceiver manufactured by Analog Devices Inc. It integrates an isolated DC/DC converter, requiring no external components. The device operates on a 3.0V to 3.6V supply (VCC) and supports a logic supply (VL) from 1.62V to 5.5V. It provides two drivers and two receivers with a maximum data rate of 1Mbps at 250pF/3kΩ load. Isolation is rated at 2500VRMS for one minute, with a common mode transient immunity of 30kV/μs. ESD protection withstands ±10kV HBM. The component is housed in a 32-pin LGA package (15mm × 11.25mm) and functions within a temperature range of -40°C to +105°C.

Drivers, Receivers, Transceivers Feature Summary

• Galvanically isolated dual RS232 interface with integrated power conversion
• High common mode transient immunity exceeding 30kV/μs
• Robust ESD protection up to ±10kV HBM without latchup
• Flexible logic interfacing via independent 1.62V to 5.5V supply pin

Drivers, Receivers, Transceivers Applications

• Isolated RS232 communication interfaces
• Industrial communication systems
• Test and measurement equipment
• Breaking RS232 ground loops in networks with different grounds

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix HY-3#PBF against official Analog Devices documentation to confirm the extended industrial temperature range (-40°C to +105°C), 3.3V nominal input voltage, and LGA-32 package type. Ensure compatibility with moisture sensitivity levels and reflow profiles specified in the datasheet before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this part for applications requiring robust isolation between disparate ground potentials. The LTM2882HY-3#PBF is suitable where high common mode transient immunity and wide operating temperature ranges are critical. Consider the 1Mbps data rate limit under standard TIA/EIA-232-F loads when designing for higher speed requirements.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTM2882 series of µModule transceivers. Variants include the CY (BGA, commercial temp), CV (LGA, commercial temp), IY (BGA, industrial temp), and IV (LGA, industrial temp). The HY suffix specifically denotes the LGA package with extended temperature capabilities.

Drivers, Receivers, Transceivers Replacement Considerations

Public confirmed substitutes include LTM2882CV-3#PBF and LTM2882IV-3#PBF. Note that these alternatives differ in package type (BGA vs LGA) or operating temperature range (commercial vs industrial). Verify pinout and thermal characteristics before substitution.
