LTC2876HMS8E#PBF

Drivers, Receivers, Transceivers Overview

The LTC2876HMS8E#PBF is a PROFIBUS RS485 transceiver in an 8-lead MSOP 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 working common mode range of ±25V, fully balanced receiver thresholds with 240mV hysteresis, and failsafe operation for open or shorted conditions. The operating temperature range extends from -40°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• Exceptional robustness against overvoltage line faults up to ±60V and high ESD immunity.
• Extended input common mode range and full failsafe operation enhance reliability in noisy environments.
• Fully balanced differential receiver thresholds with significant hysteresis ensure superior noise tolerance.

Drivers, Receivers, Transceivers Applications

• PROFIBUS IEC 61158-2 Compliant Networks
• Industrial Communication Systems
• RS485 and RS422 Data Links

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix H indicates the extended industrial temperature grade (-40°C to +125°C). Confirm the MSOP-8EP package matches the design footprint requirements. Ensure the #PBF designation aligns with lead-free manufacturing standards required by the project specifications.

Drivers, Receivers, Transceivers Selection Notes

Select this component when harsh environment fault tolerance is critical. The wide common mode range accommodates systems with significant ground potential differences. Verify that the 20Mbps maximum baud rate meets the network speed requirements without necessitating higher-performance alternatives.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2876/LTC2877 family of rugged transceivers. While the LTC2877 includes a separate logic supply pin (VL), the LTC2876 integrates logic levels with the primary power supply. Both variants share identical bus interface characteristics and protection capabilities within their respective package options.

Drivers, Receivers, Transceivers FAQ

Does the LTC2876 support low voltage logic interfacing?

No, the LTC2876 does not have a separate logic supply pin. Its logic inputs are referenced to the VCC supply, unlike the LTC2877 which supports a separate VL pin for flexible digital interfacing.

What is the maximum ESD protection rating for the bus pins?

The PA and PB interface pins are protected up to ±52kV using the Human Body Model standard.

How does the device handle receiver failsafe conditions?

The receiver includes integrated failsafe circuitry that forces the output high if the inputs are open, shorted, or terminated without being driven, preventing false triggering in noisy systems.
