LTC2862IDD-2#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2862IDD-2#TRPBF is a half-duplex RS485/RS422 transceiver in an 8-lead DFN package. It operates on a 3V to 5.5V supply with a maximum data rate of 250kbps. The device features ±60V fault protection on transmission lines and supports an extended common mode range of ±25V. It includes guaranteed failsafe receiver operation, high input impedance for up to 256 nodes, and ±15kV ESD protection on interface pins. Operating temperature ranges from -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Protected from overvoltage line faults to ±60V during all modes including power-down
• 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 on interface pins and ±8kV on other pins

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 #TRPBF indicates tape and reel packaging when sourcing. Confirm the IDD suffix corresponds to the industrial temperature grade (-40°C to +85°C). Ensure the component matches the Analog Devices manufacturer identification to avoid counterfeit parts. Cross-reference the datasheet revision against the received unit markings.

Drivers, Receivers, Transceivers Selection Notes

Select this model for applications requiring low EMI due to the slew-rate limited 250kbps data rate. It is suitable for environments with large ground loop voltages given the ±25V common mode range. Choose this part over the -1 variant if lower bandwidth is acceptable to minimize electromagnetic interference. Verify pin compatibility with legacy LT1785 or LT1791 designs if replacing existing circuitry.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC2862/LTC2863/LTC2864/LTC2865 family of low-power transceivers. The -2 suffix specifically denotes the 250kbps slew-limited version, distinguishing it from the -1 high-speed 20Mbps variant. The IDD designation identifies the industrial temperature range and DFN package configuration within the product selection guide.

Drivers, Receivers, Transceivers Replacement Considerations

The datasheet notes pin compatibility with LT1785 and LT1791 devices. Verify functional equivalence regarding fault protection levels and common mode ranges before substitution. Ensure the replacement supports the required 250kbps data rate and half-duplex operation mode.
