LTC2864CDD-2#PBF

Drivers, Receivers, Transceivers Overview

The LTC2864CDD-2#PBF 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 current-limited drivers, thermal shutdown, 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 enhanced ESD protection rated at ±15kV HBM on interface pins
• Supports high input impedance allowing connection of up to 256 nodes

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 ordering suffix against the manufacturer's official documentation to confirm the package type and temperature grade. Ensure the component matches the required duplex configuration and data rate specifications for the target application before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this model for applications requiring full-duplex communication with low electromagnetic interference due to its 250kbps slew-rate limited mode. Verify that the system ground loop voltages remain within the ±25V common mode range and that the supply voltage falls between 3V and 5.5V.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC286x family of ruggedized transceivers designed for harsh industrial environments. It shares pin compatibility with legacy parts like the LT1785 and LT1791, facilitating direct upgrades where higher fault tolerance and ESD immunity are required without redesigning the PCB layout.

Drivers, Receivers, Transceivers Replacement Considerations

LTC2864CDD-1#PBF: Identical package and electrical characteristics but configured for 20Mbps high-speed data rates instead of the 250kbps slew-limited mode.
