LTC2864CS-2#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2864CS-2#TRPBF is a 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 its low EMI slew-rate limited mode. The device features ±60V fault protection on transmission lines, ±15kV ESD protection on interface pins, and an extended common mode range of ±25V. It is housed in a 14-lead (150mil) plastic SOIC package with an operating temperature range of 0°C to 70°C.

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 current-limited drivers and thermal shutdown protection.
• Supports up to 256 nodes due to high input impedance.

Drivers, Receivers, Transceivers Applications

• Supervisory Control and Data Acquisition (SCADA)
• Industrial control and instrumentation networks
• Building automation, security systems, and HVAC

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging when sourcing this component. Confirm that the CS grade corresponds to the commercial temperature range of 0°C to 70°C for your application requirements. Ensure compatibility with standard 14-lead SOIC footprints during procurement planning.

Drivers, Receivers, Transceivers Selection Notes

Drivers, Receivers, Transceivers FAQ

What is the maximum data rate for the LTC2864CS-2?

The LTC2864CS-2 operates at a maximum data rate of 250kbps in its low EMI slew-rate limited mode.

Does this device support half-duplex operation?

No, the LTC2864 series is designed specifically for full-duplex communication.

How does the failsafe feature work?

It guarantees the receiver output will be in a logic 1 state when inputs are shorted, left open, or terminated but not driven, provided the condition persists for more than approximately 3µs.
