LTC2876IDD#PBF

Drivers, Receivers, Transceivers Overview

The LTC2876IDD#PBF is a PROFIBUS RS485 transceiver manufactured by Analog Devices Inc. It operates with a primary supply voltage (VCC) ranging from 3.0V to 5.5V, supporting standard 4.5V to 5.5V operation for full compliance. The device features a single driver and a single receiver, achieving a maximum data rate of 20Mbps. It provides robust protection against bus faults up to ±60V and offers ESD protection of ±52kV on interface pins. The component is housed in an 8-lead DFN package and supports an operating temperature range from -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Tolerates ±60V bus faults and ±52kV ESD on interface pins
• Supports PROFIBUS-DP and RS485 specifications up to 20Mbps
• Includes receiver failsafe for open, shorted, and terminated conditions
• Operates down to 3V supply voltage for low power applications

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix IDD#PBF corresponds to the industrial temperature grade (-40°C to +85°C) and DFN-8 package configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure ordering details match the exact part marking LGTM found on the lead-free finish components.

Drivers, Receivers, Transceivers Selection Notes

Select this component when PROFIBUS compliance and high fault tolerance are required. The IDD variant is suitable for industrial environments requiring extended temperature stability. Consider the LTC2877 if a separate logic supply pin (VL) is needed for flexible digital interfacing at lower voltages than the main VCC.

Drivers, Receivers, Transceivers Part Context

This device belongs to the LTC2876/LTC2877 family of rugged transceivers designed specifically for PROFIBUS applications. It shares architectural similarities with other Linear Technology interface ICs but is optimized for the specific termination and driver requirements of PROFIBUS-DP masters and slaves.

Drivers, Receivers, Transceivers Replacement Considerations

Public confirmed substitutes include the LTC2876HDD#PBF for higher temperature ranges (-40°C to +125°C) and the LTC2876CDD#PBF for commercial temperature ranges (0°C to +70°C). Other variants like the MSOP-8 package versions (e.g., LTC2876IMS8E#PBF) offer pin-compatible alternatives.
