LTC2864HDD-2#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2864HDD-2#TRPBF is a full-duplex RS485/RS422 transceiver in a 10-lead DFN package. 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, an extended common mode range of ±25V, and ±15kV ESD protection on interface pins. It includes logic-selectable enables (DE, RE) and guaranteed failsafe receiver operation.

Drivers, Receivers, Transceivers Feature Summary

• Provides ±60V overvoltage fault protection on data lines during all operational modes
• Features fully balanced differential receiver thresholds for low duty cycle distortion
• Includes high input impedance supporting up to 256 nodes on the bus
• Integrates current-limited drivers and thermal shutdown protection

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'HDD' corresponds to the 10-lead DFN package and '-2' indicates the 250kbps slew-limited variant. Confirm the '#TRPBF' designation matches tape-and-reel packaging requirements. Ensure the component meets RoHS standards as indicated by the lead-free finish specification in official documentation.

Drivers, Receivers, Transceivers Selection Notes

Select this model for applications requiring robust fault tolerance against large ground loop voltages. The 250kbps mode is suitable for environments where electromagnetic interference must be minimized through slew-rate limiting. Verify that the full-duplex architecture with separate transmit and receive lines fits the system topology.

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. The 'H' grade denotes an operating temperature range of -40°C to +125°C, distinguishing it from commercial or industrial grades within the same series.

Drivers, Receivers, Transceivers Replacement Considerations

LTC2864HDD-1#TRPBF: Identical package and temperature grade but supports 20Mbps high-speed data rates instead of 250kbps.
