LTC2863IDD-1#PBF

Drivers, Receivers, Transceivers Overview

The LTC2863IDD-1#PBF is a full-duplex RS485/RS422 transceiver from Analog Devices, housed in an 8-lead DFN package. 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 and an extended common mode range of ±25V. It includes ±15kV ESD protection on interface pins, guaranteed failsafe receiver operation, and high input impedance supporting up to 256 nodes. Operating temperature ranges from -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Protected from overvoltage line faults to ±60V during all modes of operation
• Extended common mode range of ±25V for reliable communication with large ground loop voltages
• Enhanced ESD protection allows withstand of ±15kV HBM on interface pins without latchup
• High input impedance supports connection of up to 256 nodes on the bus

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
• Medical equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix IDD-1 against official Analog Devices documentation to confirm the industrial temperature grade (-40°C to +85°C) and DFN-8 package configuration. Ensure compatibility with system voltage requirements of 3V to 5.5V. Confirm that the full-duplex topology matches the application design before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when full-duplex communication is required alongside robust fault tolerance. The IDD-1 variant provides the industrial temperature range suitable for harsh environments. Consider the 20Mbps data rate capability and the need for ±60V line protection when evaluating alternatives for noisy industrial networks.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC286x family of low-power, fault-protected transceivers. It shares pinout compatibility with legacy parts like the LT1785 and LT1791. The 'IDD' suffix indicates the DFN-8 package and industrial temperature range, while '-1' specifies the 20Mbps data rate version within the full-duplex LTC2863 series.

Drivers, Receivers, Transceivers Replacement Considerations

LT1785 and LT1791 are pin-compatible alternatives mentioned in the datasheet. Verify electrical specifications such as fault protection levels and data rates when substituting.
