LTC2876IMS8E#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2876IMS8E#TRPBF is a PROFIBUS RS485 transceiver in an 8-lead MSOP package. It operates with a supply voltage of 3V to 5.5V and supports data rates up to 20Mbps. The device tolerates ±60V bus faults and provides ±52kV ESD protection on interface pins. Key electrical parameters include a common mode input range of ±25V, a receiver hysteresis of 240mV, and a shutdown current of less than 25µA. It meets IEC 61158-2 Type 3 specifications.

Drivers, Receivers, Transceivers Feature Summary

• Exceptional robustness with ±60V fault tolerance and ±52kV ESD protection on bus pins
• Compliant with PROFIBUS-DP masters/slaves and IEC 61158-2 Type 3 MAU standards
• High receiver input resistance allows connection of up to 200 nodes per network
• Fully balanced differential receiver thresholds with 240mV hysteresis for superior noise tolerance

Drivers, Receivers, Transceivers Applications

• PROFIBUS-DP compliant industrial communication networks
• Harsh environments requiring protection against overvoltage line faults
• RS485 and RS422 systems operating in noisy conditions
• Low power applications utilizing 3V supply operation

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the IMS8E designation corresponds to the industrial temperature range of –40°C to 85°C. Ensure the component matches the 8-lead MSOP physical footprint required for the target PCB layout. Cross-reference the manufacturer part number with official distributor catalogs to confirm authenticity.

Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring high node counts due to its low unit load characteristics. It is suitable for systems exposed to significant electrical noise or potential bus faults. Consider the 20Mbps maximum baud rate for high-speed requirements. Verify that the 3V to 5.5V supply range aligns with the system power architecture.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2876/LTC2877 family of rugged transceivers. The LTC2876 variant lacks a separate logic supply pin, unlike the LTC2877. Both share identical driver and receiver performance metrics. The IMS8E package variant offers a compact surface-mount solution for space-constrained industrial boards.
