LTC2876CMS8E#PBF

Drivers, Receivers, Transceivers Overview

The LTC2876CMS8E#PBF is a PROFIBUS RS485 transceiver manufactured by Analog Devices Inc. It operates with a supply voltage range of 3.0V to 5.5V, supporting standard 4.5V to 5.5V operation and low-power 3.0V mode. The device features a maximum data rate of 20Mbps and includes one driver and one receiver for half-duplex communication. It provides ±60V fault tolerance on bus pins and ±52kV ESD protection on interface pins. The component is housed in an 8-lead MSOP package with an exposed pad and supports an operating temperature range from -40°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• Exceptional robustness with ±60V fault tolerance on bus pins and ±52kV ESD protection on interface pins.
• Extended ±25V input common-mode range combined with full failsafe operation for reliable data communication in noisy environments.
• Fully balanced differential receiver thresholds with 240mV hysteresis to ensure superior noise tolerance and low duty cycle distortion.
• Compliance with PROFIBUS-DP masters and slaves specifications while maintaining compatibility with IEC 61158-2 Type 3 MAU standards.

Drivers, Receivers, Transceivers Applications

• PROFIBUS IEC 61158-2 Compliant Networks
• Industrial Communication Systems
• RS485 and RS422 Data Transmission Interfaces

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix CMS8E corresponds to the commercial temperature grade (0°C to 70°C) as indicated in the ordering information table. Confirm that the #PBF designation ensures lead-free finish compliance. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity and traceability before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when harsh environment protection is required, specifically where ±60V line faults or high ESD events are anticipated. Choose the LTC2876 over the LTC2877 if a separate logic supply pin is not needed, as it shares the VCC supply for both analog and digital sections. Ensure the application does not require the extended logic voltage flexibility provided by the VL pin found in the LTC2877 variant.

Drivers, Receivers, Transceivers Part Context

This device belongs to the LTC2876/LTC2876 family of rugged PROFIBUS transceivers designed for industrial automation. It complements other Analog Devices interface solutions by offering specialized protection against electrical overstress. The MSOP-8EP package allows for compact PCB layouts while maintaining thermal performance through the exposed pad connection.

Drivers, Receivers, Transceivers Replacement Considerations

LTC2876IMS8E#PBF offers the same functionality with an extended industrial temperature range (-40°C to 85°C). LTC2876HMS8E#PBF provides the same function with a high-temperature range (-40°C to 125°C). Verify temperature requirements before substituting, as the CMS8E variant is limited to commercial temperatures (0°C to 70°C).
