LTC2876HDD#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2876HDD#TRPBF is a PROFIBUS RS485 transceiver in an 8-lead DFN package. It supports data rates up to 20 Mbps and operates with a supply voltage of 3V to 5.5V, drawing 750 µA at 5V. The device tolerates ±60V bus faults and provides ±52kV ESD protection on interface pins. It features a 240mV receiver hysteresis for noise immunity and includes failsafe logic for open or shorted bus conditions.

Drivers, Receivers, Transceivers Feature Summary

• Robust fault tolerance with ±60V bus pin protection and ±52kV ESD rating
• High-speed differential signaling supporting up to 20 Mbps data rates
• Integrated 240mV hysteresis and failsafe thresholds for reliable operation in noisy environments

Drivers, Receivers, Transceivers Applications

• PROFIBUS-DP master and slave networks
• Industrial communication systems requiring high noise immunity
• RS485 and RS422 multi-node interfaces

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm the H-grade designation matches the required -40°C to +125°C operating temperature range for your application environment. Ensure the DFN-8 footprint aligns with your PCB layout constraints.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications demanding ruggedness against overvoltage line faults. It is suitable for harsh industrial settings where 24V power might be inadvertently connected. Consider the 8-lead DFN package for space-constrained designs requiring PROFIBUS compliance without additional external protection circuitry.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2876/LTC2877 family of rugged transceivers designed specifically for PROFIBUS standards. The 'H' suffix denotes the extended industrial temperature range, while 'DD' specifies the plastic DFN package. The '#TRPBF' suffix confirms lead-free finish and tape-and-reel delivery format.

Drivers, Receivers, Transceivers FAQ

Does the LTC2876 support low-voltage logic interfacing?

No, the LTC2876 uses the VCC supply for logic levels. Only the LTC2877 variant offers a separate VL pin for flexible digital interfacing down to 1.65V.

What is the maximum common-mode input voltage?

The device supports a working common mode range of ±25V, allowing reliable data reception even under significant bus offset conditions.
