LTC2864CDD-2#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2864CDD-2#TRPBF is a low-power, full-duplex RS-422/RS-485 transceiver manufactured by Analog Devices Inc. It operates on a 3V to 5.5V supply voltage and supports a maximum data rate of 250kbps in slew-rate limited mode. The device features ±60V fault protection on transmission lines and ±15kV ESD protection on interface pins. It utilizes an 8-lead (3mm × 3mm) plastic DFN package with an exposed pad connected to PCB ground. The component guarantees failsafe receiver operation and includes thermal shutdown protection.

Drivers, Receivers, Transceivers Feature Summary

• Protected from overvoltage line faults up to ±60V during all modes of operation
• Enhanced ESD protection withstands ±15kV HBM on interface pins without latchup
• Extended common mode range of ±25V improves reliability in noisy environments
• Guaranteed failsafe receiver operation ensures logic high state when inputs are unconnected

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 against official manufacturer documentation to confirm package type and temperature grade. Ensure the part number matches the required duplex configuration and data rate specifications for the target application design.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring robust fault tolerance on RS-485 or RS-422 buses. The 250kbps slew-rate limited mode is suitable for reducing electromagnetic interference. Verify that the system ground loop voltages remain within the ±25V common mode input range.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC286x family of fault-protected transceivers. It shares pin compatibility with legacy parts like the LT1785 and LT1791. The 'C' designation indicates a commercial temperature range, while 'IDD' specifies the DFN package variant.

Drivers, Receivers, Transceivers Replacement Considerations

Publicly confirmed substitutes include other members of the LTC2864 series such as LTC2864IS-2#PBF or LTC2864HS-2#PBF, provided they match the required operating temperature range and package style.
