LTC2863IDD-2#PBF

Drivers, Receivers, Transceivers Overview

The LTC2863IDD-2#PBF is a low-power, full-duplex RS485/RS422 transceiver manufactured by Analog Devices Inc. It operates on a 3V to 5.5V supply voltage and supports a maximum data rate of 250kbps with slew-rate limiting for low EMI applications. The device features ±60V fault protection on the A, B, Y, and Z pins during all modes, including power-down. It provides ±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 connected to PCB ground, it operates within a temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Protected from overvoltage line faults up to ±60V on transmission lines
• Guaranteed failsafe receiver operation with fully balanced differential thresholds
• High input impedance supporting up to 256 nodes on the bus
• Enhanced ESD protection with ±15kV HBM rating on interface pins

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and temperature grade. Ensure the component matches the required duplex configuration and data rate specifications for the target application. Cross-reference the part number with authorized distributors to confirm availability and authenticity before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring full-duplex communication with robust fault protection. The IDD suffix indicates an industrial temperature range (-40°C to +85°C) and DFN packaging. Verify that the 250kbps slew-limited data rate meets system timing requirements. Confirm compatibility with existing logic levels and ensure adequate thermal management for the DFN package.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2862/LTC2863/LTC2864/LTC2865 family of low-power RS485/RS422 transceivers. It shares pinout compatibility with legacy parts like the LT1785 and LT1791. The 'IDD' designation specifies the 8-lead DFN package and industrial temperature range, while the '-2' suffix denotes the 250kbps data rate variant.

Drivers, Receivers, Transceivers Replacement Considerations

The datasheet confirms pin compatibility with LT1785 and LT1791 devices. Verify electrical parameters such as supply voltage and fault protection ratings when substituting these legacy components.
