LTC2862CS8-2#TRPBF

Drivers, Receivers, Transceivers Overview

The Analog Devices LTC2862CS8-2#TRPBF is a half-duplex RS485/RS422 transceiver in an 8-lead SOIC package. It operates on a 3V to 5.5V supply and supports data rates up to 20Mbps or low EMI 250kbps. The device features ±60V overvoltage fault protection on interface pins, ±15kV ESD protection, and an extended common mode range of ±25V. It includes current-limited drivers, thermal shutdown, and guaranteed failsafe receiver operation.

Drivers, Receivers, Transceivers Feature Summary

• Protected from overvoltage line faults to ±60V during all modes including power-down
• Enhanced ESD protection with ±15kV HBM rating on interface pins
• Extended common mode input range of ±25V for reliable communication in noisy environments
• Guaranteed failsafe receiver operation with fully balanced differential thresholds

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 #TRPBF indicates tape and reel packaging when sourcing components. Confirm the CS8 designation corresponds to the commercial temperature grade of 0°C to 70°C. Ensure the ordering information matches the required lead-free finish and plastic SOIC package type for your assembly process.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring robust fault protection against high voltage ground loops. The 250kbps slew-rate limited mode is suitable for reducing electromagnetic interference in sensitive industrial settings. Verify that the half-duplex configuration meets the bidirectional communication requirements of the target network topology.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2862 series of low-power RS485/RS422 transceivers. It is pin-compatible with legacy parts like the LT1785 and LT1791, facilitating direct upgrades. The CS8 variant specifically denotes the commercial temperature range within the broader family that includes industrial and military grade options.

Drivers, Receivers, Transceivers Replacement Considerations

LTC2862CS8-2#PBF is the tube version of the same electrical specification. For wider temperature ranges, consider LTC2862IS8-2#TRPBF (-40°C to 85°C) or LTC2862HS8-2#TRPBF (-40°C to 125°C). Higher speed variants include the LTC2862CS8-1#TRPBF.
