LTC2876CDD#PBF

Drivers, Receivers, Transceivers Overview

The LTC2876CDD#PBF is a rugged PROFIBUS and RS485 transceiver manufactured by Analog Devices Inc. It operates with a primary supply voltage (VCC) of 4.5V to 5.5V, supporting operation down to 3V for low-power applications. The device features a maximum data rate of 20Mbps and tolerates ±60V faults on bus pins PA and PB. It provides ±52kV ESD protection on interface pins and ±15kV on other pins. The receiver input common-mode range extends to ±25V with a 240mV hysteresis threshold. It is housed in an 8-lead DFN package (3mm x 3mm) and supports an operating temperature range of 0°C to 70°C.

Drivers, Receivers, Transceivers Feature Summary

• Exceptional robustness against overvoltage line faults up to ±60V and high-voltage ESD events.
• Compliance with PROFIBUS-DP masters/slaves specifications and IEC 61158-2 Type 3 MAU standards.
• High receiver input resistance enabling support for up to 200 nodes per contiguous network.
• Fully balanced differential receiver thresholds with integrated hysteresis for superior noise tolerance.

Drivers, Receivers, Transceivers Applications

• PROFIBUS-DP networks compliant with IEC 61158-2
• Industrial communication systems requiring high noise immunity
• RS485 and RS422 multi-node communication links
• Harsh environments subject to 24V power connection errors

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix #PBF indicates lead-free finish and RoHS compliance when sourcing. Confirm the C suffix corresponds to the commercial temperature range of 0°C to 70°C. Ensure the DDD package designation matches the required 8-lead DFN footprint for PCB layout compatibility.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring strict PROFIBUS compliance and high fault tolerance. The LTC2876 lacks the separate logic supply pin found in the LTC2877; verify if independent logic interfacing is necessary. Consider the H or I suffix variants if operation below 0°C or above 70°C is required.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2876/LTC2877 family of rugged transceivers designed for industrial fieldbus applications. The LTC2876 variant specifically integrates all logic supplies internally, whereas the LTC2877 offers a separate VL pin for flexible digital interfacing. Both share identical bus interface robustness characteristics.

Drivers, Receivers, Transceivers Replacement Considerations

Public confirmed substitutes include the LTC2877 series for similar functionality with added logic supply flexibility. Verify pinout compatibility between DFN-8 packages before substitution.
