LTC2876IMS8E#PBF

Drivers, Receivers, Transceivers Overview

The LTC2876IMS8E#PBF is a rugged PROFIBUS and RS485 transceiver in an 8-lead MSOP package. It operates with a primary supply (VCC) of 4.5V to 5.5V, supporting data rates up to 20Mbps. The device tolerates ±60V bus faults and offers ±52kV ESD protection on interface pins. It features a ±25V common mode input range and full failsafe operation. The receiver provides balanced thresholds with 240mV hysteresis for noise tolerance. Unlike the LTC2877, this model lacks a separate logic supply pin.

Drivers, Receivers, Transceivers Feature Summary

• Designed to meet PROFIBUS-DP master and slave test specifications and IEC 61158-2 Type 3 MAU standards.
• Exceptional robustness with ±60V fault tolerance on bus pins and ±52kV ESD protection on interface pins.
• Full failsafe receiver operation ensures high output state during open, shorted, or terminated bus conditions.
• Balanced differential receiver thresholds with 240mV hysteresis provide superior noise tolerance and low duty cycle distortion.

Drivers, Receivers, Transceivers Applications

• PROFIBUS-DP compliant industrial communication networks
• RS485 and RS422 multi-node systems
• Harsh industrial environments requiring overvoltage line fault protection

Drivers, Receivers, Transceivers Procurement Notes

Verify the IMS8E suffix confirms the Industrial temperature range (-40°C to 85°C) and MSOP-8 package. Confirm the #PBF suffix indicates lead-free finish compliance. Ensure the ordering code matches the specific lot traceability requirements for your manufacturing process. Cross-reference the manufacturer's latest order information sheet for any packaging quantity updates.

Drivers, Receivers, Transceivers Selection Notes

Select this component when PROFIBUS compliance is mandatory without the need for a separate low-voltage logic supply. The LTC2876 integrates all logic functions into the VCC domain, simplifying power design compared to the LTC2877. It is suitable for systems where the microcontroller logic voltage matches the transceiver supply voltage. Verify that the 200-node receiver load capability meets network expansion requirements.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2876/LTC2877 family of rugged transceivers. The LTC2876 differs from the LTC2877 by omitting the VL logic supply pin, tying all logic levels to VCC. Both share identical driver/receiver electrical characteristics and protection features. The IMS8E variant specifically denotes the industrial temperature grade within the MSOP-8 plastic package offering.

Drivers, Receivers, Transceivers Replacement Considerations

Publicly confirmed substitutes include the LTC2876CMS8E#PBF for commercial temperature range and LTC2876HMS8E#PBF for extended temperature range. Direct functional replacements require matching the MSOP-8 footprint and pinout. Verify thermal performance if replacing with higher temperature variants in constrained enclosures.
