LTC2864IDD-2#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2864IDD-2#TRPBF is a low-power, full-duplex RS485/RS422 transceiver manufactured by Analog Devices Inc. It operates on a 3V to 5.5V supply and supports a maximum data rate of 250kbps with slew-rate limiting for low EMI. The device features ±60V fault protection on transmission lines during all modes, including power-down. It provides an extended common mode range of ±25V and includes ±15kV ESD protection on interface pins. Packaged in a 10-lead (3mm × 3mm) plastic DFN, it operates within a temperature range of –40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Full-duplex operation with independent driver and receiver channels
• ±60V overvoltage fault protection on A, B, Y, and Z pins
• Slew-rate limited 250kbps data rate for reduced electromagnetic interference
• Extended ±25V common mode input voltage range

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 of –40°C to +85°C. Ensure the package type matches the 10-lead DFN footprint requirements for the target PCB design. Cross-reference the manufacturer's latest datasheet for any updates to electrical characteristics or pin configurations.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring robust fault tolerance against high ground loop voltages up to ±60V. The 250kbps slew-limited mode is suitable for noise-sensitive environments where EMI reduction is critical. Verify that the system logic levels are compatible with the VCC supply voltage. Consider the thermal performance of the exposed pad in the DFN package for high-power dissipation scenarios.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC286x family of fault-protected transceivers from Analog Devices. It shares pin compatibility with legacy parts like the LT1785 and LT1791. The 'IDD' designation specifies the industrial temperature range and DFN package. The '#TRPBF' suffix denotes lead-free tape and reel packaging for automated assembly.

Drivers, Receivers, Transceivers Replacement Considerations

LTC2864ISD-2#TRPBF: Same function with commercial temperature range (0°C to 70°C). LTC2864HSD-2#TRPBF: Same function with automotive/high temperature range (–40°C to 125°C). LTC2864MPS-2#TRPBF: Military-grade option (–55°C to 125°C). LT1785/LT1791: Pin-compatible legacy alternatives without integrated ±60V fault protection.
