LTC2876IDD#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2876IDD#TRPBF is a PROFIBUS RS485 transceiver in an 8-lead DFN 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, fully balanced receiver thresholds with 240mV hysteresis, and integrated failsafe for open or shorted conditions. Operating temperature range is -40°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• PROFIBUS-DP compliant with IEC 61158-2 Type 3 MAU specifications
• Robust fault tolerance with ±60V bus pin protection and ±52kV ESD rating
• High noise immunity via 240mV balanced receiver hysteresis and failsafe logic
• Extended common mode range supporting ±25V working voltage

Drivers, Receivers, Transceivers Applications

• PROFIBUS industrial communication networks
• RS485 and RS422 multi-drop systems
• Harsh environments requiring overvoltage line fault protection
• Low power differential signaling applications operating at 3V

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix IDD indicates the industrial temperature grade (-40°C to +85°C) and DFN-8 package configuration. Confirm the TRPBF suffix denotes tape and reel packaging. Cross-reference the manufacturer part number against official Analog Devices documentation to ensure authenticity and correct revision level before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when PROFIBUS compliance and high robustness are required. The LTC2876 lacks the separate VL logic supply found in the LTC2877, making it suitable for single-supply logic interfacing. Ensure the application does not require the extended -40°C to +125°C range, which requires the H-grade variant.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC2876/LTC2877 family of rugged PROFIBUS transceivers. It serves as the non-isolated, single-supply counterpart to the LTC2877, which includes a dedicated low-voltage logic supply pin. Both devices share identical electrical performance regarding bus robustness and data rate capabilities.

Drivers, Receivers, Transceivers Replacement Considerations

LTC2876HDD#TRPBF offers the same functionality with an extended temperature range of -40°C to +125°C.
