LTC2877HMSE#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2877HMSE#TRPBF is a rugged PROFIBUS and RS485 transceiver designed for harsh industrial environments. It supports data rates up to 20Mbps and tolerates ±60V bus faults with ±52kV ESD protection on interface pins. The device features a primary supply (VCC) of 3.0V to 5.5V and a separate logic supply (VL) ranging from 1.65V to VCC, enabling flexible digital interfacing. It operates within an extended temperature range of –40°C to 125°C and is housed in a 10-lead MSOP package.

Drivers, Receivers, Transceivers Feature Summary

• Integrated 1.65V to 5.5V logic supply pin for low-voltage microcontroller interfacing
• Exceptional robustness with ±60V fault tolerance and ±52kV ESD protection on bus pins
• Extended ±25V common-mode input range with full failsafe operation for noisy systems
• Fully balanced differential receiver thresholds with 240mV hysteresis for superior noise tolerance

Drivers, Receivers, Transceivers Applications

• PROFIBUS-DP compliant networks
• Industrial communication systems
• RS485 and RS422 multi-drop buses
• 3V low voltage differential signaling applications

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the HMSE designation corresponds to the high-temperature grade (-40°C to 125°C) and MSOP-10 package. Ensure compatibility with the required logic voltage levels provided by the VL pin before finalizing procurement specifications.

Drivers, Receivers, Transceivers Selection Notes

Select the LTC2877 over the LTC2876 when independent logic supply voltage is required for interfacing with 1.8V or 3.3V controllers. Verify that the application requires the specific PROFIBUS termination characteristics and high node count capabilities supported by this transceiver family.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC2876/LTC2877 series of rugged transceivers. The 'H' suffix denotes the extended industrial temperature range, while 'MSE' specifies the 10-lead MSOP package. The '#TRPBF' suffix indicates lead-free finish and tape-and-reel delivery format.

Drivers, Receivers, Transceivers Replacement Considerations

The LTC2876HMSE#TRPBF is a direct functional substitute if the separate logic supply pin is not utilized. Other RS485 transceivers may require external biasing and lack the specific PROFIBUS compliance testing.
