LTC2876CDD#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2876CDD#TRPBF is a PROFIBUS RS485 transceiver in an 8-lead DFN package. It supports data rates up to 20Mbps and operates with a VCC supply of 3V to 5.5V. The device tolerates ±60V bus faults and provides ±52kV ESD protection on interface pins. It features a 240mV hysteresis receiver threshold for noise immunity and includes failsafe logic for open or shorted bus conditions. The component operates within a temperature range of 0°C to 70°C.

Drivers, Receivers, Transceivers Feature Summary

• Robust fault tolerance with ±60V overvoltage protection on bus pins
• High ESD immunity rated at ±52kV on interface pins
• Balanced differential receiver thresholds with 240mV hysteresis
• Integrated failsafe operation for open, shorted, and terminated bus states

Drivers, Receivers, Transceivers Applications

• PROFIBUS-DP master and slave networks
• Industrial communication systems requiring high noise immunity
• RS485 and RS422 multi-node serial interfaces
• Harsh environments with potential 24V power line faults

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix CDD#TRPBF against the manufacturer's current ordering guide to confirm lead-free status and tape-and-reel packaging specifications. Ensure the component meets RoHS directives for your region. Cross-reference the part marking LGTM with the datasheet to authenticate the source before integration into production assemblies.

Drivers, Receivers, Transceivers Selection Notes

Select this model when a single driver and receiver are required without a separate logic supply pin. The LTC2876 integrates all logic functions onto the primary VCC rail, simplifying power distribution compared to the LTC2877 variant. This configuration is optimal for standard 5V or 3.3V digital interfacing where independent low-voltage logic isolation is not necessary.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC2876/LTC2877 family of rugged transceivers designed specifically for PROFIBUS compliance. The series distinguishes itself through superior common-mode rejection and extended input ranges compared to standard RS485 devices. The DFN package offers a compact footprint suitable for dense industrial control board layouts.
