LTC2863CDD-1#PBF

Drivers, Receivers, Transceivers Overview

The LTC2863CDD-1#PBF is a full-duplex RS485/RS422 transceiver manufactured by Analog Devices Inc. It operates on a 3V to 5.5V supply and supports data rates up to 20Mbps. The device features ±60V fault protection on transmission lines, ±15kV ESD protection on interface pins, and an extended common mode range of ±25V. Packaged in an 8-lead DFN (3mm × 3mm) with an exposed pad, it functions within a commercial temperature range of 0°C to 70°C.

Drivers, Receivers, Transceivers Feature Summary

• Provides ±60V overvoltage fault protection on data lines during all operational modes including power-down.
• Features enhanced ESD protection rated at ±15kV HBM on interface pins and ±8kV on other pins.
• Supports high impedance input allowing connection of up to 256 nodes on the bus.
• Includes guaranteed failsafe receiver operation to maintain logic high state during idle or open line conditions.

Drivers, Receivers, Transceivers Applications

• Supervisory Control and Data Acquisition (SCADA)
• Industrial control and instrumentation networks
• Automotive and transportation electronics
• Building automation, security systems, and HVAC

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'CDD-1' corresponds to the commercial temperature grade and single-driver configuration. Confirm the package type matches the 8-lead DFN footprint requirements for the target PCB layout. Ensure the ordering code includes the '#PBF' designation for lead-free compliance if required by assembly specifications.

Drivers, Receivers, Transceivers Selection Notes

Select this component when full-duplex communication is required alongside robust fault tolerance. The C-grade variant is suitable for standard commercial environments operating between 0°C and 70°C. Consider the IDD-1 suffix if an industrial temperature range (-40°C to 85°C) is necessary for the application environment.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC286x family of rugged transceivers designed for harsh electrical environments. It shares pin compatibility with legacy LT1785 and LT1791 devices, facilitating direct upgrades. The series distinguishes itself through integrated BiCMOS technology that enables high-voltage tolerance without external protection components.

Drivers, Receivers, Transceivers Replacement Considerations

LT1785 and LT1791 are pin-compatible alternatives within the same product family. Verify that the replacement part meets the specific duplex requirement and temperature grade needed for the design.
