LTC2877CMSE#PBF

Drivers, Receivers, Transceivers Overview

The LTC2877CMSE#PBF is a PROFIBUS RS485 transceiver in a 10-lead MSOP package. It features a primary power supply (VCC) range of 3.0V to 5.5V and a separate logic interface supply (VL) ranging from 1.65V to VCC. The device supports data rates up to 20Mbps with a maximum differential output voltage of 7V peak-to-peak under PROFIBUS loads. It tolerates ±60V bus faults, provides ±52kV ESD protection on interface pins, and operates within a temperature range of –40°C to 125°C.

Drivers, Receivers, Transceivers Feature Summary

• Supports PROFIBUS-DP masters and slaves with full IEC 61158-2 compliance
• Features a dedicated low-voltage logic supply for flexible digital interfacing
• Provides exceptional robustness against overvoltage line faults up to ±60V
• Includes integrated receiver failsafe for open, shorted, and terminated conditions

Drivers, Receivers, Transceivers Applications

• PROFIBUS industrial communication networks
• Harsh environment RS485 systems requiring high fault tolerance
• Industrial automation nodes with 24V power connection risks

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix CMSE corresponds to the commercial temperature grade and MSOP-10 package configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the logic supply pin VL is correctly decoupled to maintain signal integrity at varying data rates.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a separate logic supply voltage is required to interface with lower voltage microcontrollers while maintaining a standard 5V bus supply. The 10-lead MSOP package offers a compact footprint suitable for space-constrained PCB layouts. Verify that the application requires PROFIBUS-specific termination characteristics rather than standard RS485 configurations.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2876/LTC2877 family of rugged PROFIBUS transceivers. The LTC2877 variant is distinguished by its additional logic supply pin, enabling independent control of the digital interface voltage level. This family is engineered specifically for medium attachment units in industrial fieldbus applications.
