LTC2877CDD#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2877CDD#TRPBF is a PROFIBUS and RS485 transceiver in an 8-lead DFN package. It features a dedicated logic supply pin (VL) supporting 1.65V to 5.5V for flexible digital interfacing, while the primary power supply (VCC) operates from 3.0V to 5.5V. The device supports data rates up to 20Mbps with ±60V fault tolerance on bus pins and ±52kV ESD protection. It includes full failsafe operation, balanced receiver thresholds with 240mV hysteresis, and operates within a temperature range of –40°C to 125°C.

Drivers, Receivers, Transceivers Feature Summary

• Dedicated low-voltage logic interface supply pin for flexible digital interfacing
• Exceptional robustness with ±60V bus fault tolerance and high ESD protection
• Full failsafe receiver operation ensuring reliable communication in noisy environments
• High input resistance allowing connection of up to 200 nodes per network

Drivers, Receivers, Transceivers Applications

• PROFIBUS-DP compliant industrial communication networks
• RS485 and RS422 differential signaling systems
• Harsh industrial environments requiring overvoltage line fault protection
• 3V low voltage differential signaling applications

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm that the CDD designation corresponds to the plastic DFN package variant. Ensure the ordering information matches the required operating temperature range for the intended application environment before finalizing procurement.

Drivers, Receivers, Transceivers Selection Notes

Select the LTC2877 over the LTC2876 when a separate logic supply voltage is required to interface with lower voltage microcontrollers or processors. Verify that the system design accommodates the 10-lead DFN footprint associated with the DD package suffix. Ensure the primary supply voltage meets the minimum requirements for PROFIBUS compliance if strict standard adherence is necessary.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC2876/LTC2877 family of rugged transceivers designed specifically for PROFIBUS and RS485 applications. The series distinguishes itself through high fault tolerance and compatibility with IEC 61158-2 standards. The LTC2877 variant adds a dedicated logic supply pin compared to the LTC2876, offering greater flexibility in mixed-voltage system designs.

Drivers, Receivers, Transceivers Replacement Considerations

LTC2876CDD#TRPBF serves as a direct functional substitute if the separate logic supply pin is not utilized in the circuit design.
