LTC2877HDD#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2877HDD#TRPBF is a rugged PROFIBUS and RS485 transceiver in a 10-lead DFN package. It features a ±60V fault-tolerant bus interface with ±52kV ESD protection on line pins. The device supports data rates up to 20Mbps and operates with a primary supply (VCC) of 3.0V to 5.5V. A distinct logic supply pin (VL) allows for flexible digital interfacing from 1.65V to VCC. Electrical characteristics include a common-mode input range of ±25V, 240mV receiver hysteresis, and shutdown currents as low as 5µA.

Drivers, Receivers, Transceivers Feature Summary

• Integrated separate logic supply pin enabling independent voltage levels for digital control signals
• High robustness against overvoltage faults and electrostatic discharge on the communication bus
• Balanced differential receiver thresholds providing superior noise tolerance and signal integrity

Drivers, Receivers, Transceivers Applications

• PROFIBUS-DP compliant industrial networks
• Harsh environment RS485 and RS422 systems
• Low voltage differential signaling applications

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix matches the required temperature grade and packaging format. Confirm that the logic supply pin configuration aligns with the system's digital interface requirements. Ensure the ordering information corresponds to the exact component specifications needed for the design.

Drivers, Receivers, Transceivers Selection Notes

Select this model when a dedicated logic supply rail is necessary to interface with lower voltage microcontrollers while maintaining a standard 5V bus supply. The 10-lead DFN package offers a compact footprint suitable for space-constrained PCB layouts requiring high-density routing.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC2876/LTC2877 family of rugged transceivers. The distinguishing factor between the LTC2876 and LTC2877 is the inclusion of the VL pin on the latter, which provides isolated power for logic inputs and outputs. Both variants share identical bus protection and driver performance characteristics.

Drivers, Receivers, Transceivers Replacement Considerations

LTC2876HDD#TRPBF serves as a functional substitute if the logic supply pin is not utilized or can be tied to the main supply.
