LTC2877CDD#PBF

Drivers, Receivers, Transceivers Overview

The LTC2877CDD#PBF is a PROFIBUS and RS485 transceiver in an 8-lead DFN package. It features a separate logic supply (VL) ranging from 1.65V to VCC, enabling flexible digital interfacing with low-voltage controllers. The primary power supply (VCC) operates between 3.0V and 5.5V. It supports data rates up to 20Mbps and tolerates ±60V bus faults with ±52kV ESD protection on interface pins.

Drivers, Receivers, Transceivers Feature Summary

• Separate logic supply pin for flexible digital interfacing
• Exceptional robustness against overvoltage line faults
• High receiver input resistance supporting extensive network nodes

Drivers, Receivers, Transceivers Applications

• PROFIBUS-DP compliant networks
• Industrial communication systems
• RS485 and RS422 differential signaling applications

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix matches the required temperature range and packaging format. Confirm that the logic supply voltage requirements align with the host microcontroller's I/O levels before finalizing the order.

Drivers, Receivers, Transceivers Selection Notes

Select this model when a dedicated logic supply is needed to interface with 1.65V or 3.3V logic while maintaining a standard 5V bus supply. Ensure the application requires the specific DFN-8 footprint and thermal characteristics provided by this package type.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC2876/LTC2877 family of rugged transceivers. The distinguishing feature of the LTC2877 variant is the inclusion of a separate VL pin, allowing independent control of the logic interface voltage compared to the integrated supply design of the LTC2876.

Drivers, Receivers, Transceivers Replacement Considerations

LTC2876CDD#PBF serves as a functional substitute if the application does not require a separate logic supply voltage and can operate with a unified VCC rail for both logic and bus interfaces.
