LTC2876CMS8E#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2876CMS8E#TRPBF is a PROFIBUS RS485 transceiver in an 8-lead MSOP package. It operates with a VCC supply of 3V to 5.5V and supports data rates up to 20Mbps. The device tolerates ±60V bus faults and provides ±52kV ESD protection on interface pins. It features a wide ±25V common mode input range, balanced receiver thresholds with 240mV hysteresis, and integrated failsafe for open or shorted conditions. Operating temperature range is 0°C to 70°C.

Drivers, Receivers, Transceivers Feature Summary

• Exceptional robustness against overvoltage line faults up to ±60V and high ESD immunity.
• Compliant with PROFIBUS-DP masters/slaves and IEC 61158-2 Type 3 MAU specifications.
• Wide operating common mode range and full failsafe operation enhance reliability in noisy environments.

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm the CMS8E designation corresponds to the commercial temperature grade (0°C to 70°C) required for the target application environment. Ensure compatibility with standard MSOP-8 footprints during PCB layout verification.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring strict PROFIBUS compliance alongside high fault tolerance. The 8-pin MSOP package suits space-constrained designs. Consider the LTC2877 if a separate low-voltage logic supply pin is necessary for interfacing with 1.8V microcontrollers.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2876/LTC2877 family of rugged transceivers designed for harsh industrial environments. The series addresses the limitations of standard RS485 devices by offering superior voltage handling and noise immunity specifically tuned for PROFIBUS network requirements.
