LTC2865HDE#PBF

Drivers, Receivers, Transceivers Overview

The LTC2865HDE#PBF is a full-duplex RS-485/RS-422 transceiver in a 12-lead DFN package. It operates on a 3V to 5.5V supply and supports data rates of 20Mbps or 250kbps via a logic-selectable slew rate option. The device features ±60V fault protection, an extended common mode range of ±25V, and ±15kV ESD protection on interface pins. A dedicated VL pin allows flexible digital interface voltages from 1.65V to 5.5V.

Drivers, Receivers, Transceivers Feature Summary

• Integrated ±60V overvoltage fault protection on transmission lines during all operational modes
• Logic-selectable high-speed (20Mbps) or low EMI (250kbps) data transmission modes
• Dedicated logic supply pin enabling independent voltage levels for digital interfaces
• Guaranteed failsafe receiver operation with fully balanced differential thresholds

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 suffix against official documentation to confirm temperature grade and packaging format. Ensure the component matches the required duplex configuration and logic supply requirements for the target application design.

Drivers, Receivers, Transceivers Selection Notes

Select this model for applications requiring full-duplex communication with flexible logic voltage levels. Consider the slew rate selection pin for EMI reduction versus maximum throughput requirements. Verify thermal management needs for the DFN package in enclosed environments.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC286x family of fault-protected transceivers. It shares pin compatibility with legacy parts like the LT1785 and LT1791 while offering enhanced overvoltage tolerance and flexible logic interface capabilities not found in older generations.

Drivers, Receivers, Transceivers Replacement Considerations

The datasheet confirms pin compatibility with the LT1785 and LT1791. Verify that substitute components support the same ±60V fault protection and extended common mode range specifications.
