LTC2862HS8-2#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2862HS8-2#TRPBF is a half-duplex RS-485/RS-422 transceiver manufactured by Analog Devices. It operates on a 3V to 5.5V supply and supports data rates of up to 20Mbps or low EMI 250kbps. The device features ±60V overvoltage fault protection on interface pins during all modes, including power-down. It provides ±15kV ESD protection on interface pins and an extended common mode range of ±25V. Packaged in an 8-lead SOIC (S8) with tape and reel delivery, it functions within a temperature range of -40°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• Protected from overvoltage line faults to ±60V
• Extended common mode range of ±25V for noisy environments
• Guaranteed failsafe receiver operation with high input impedance supporting 256 nodes
• Enhanced ESD protection with ±15kV on interface pins

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 #TRPBF confirms tape and reel packaging rather than tube. Confirm the HS grade indicates the -40°C to +125°C industrial temperature range. Ensure the S8 package matches the PCB footprint requirements. Cross-reference the manufacturer part number against official Analog Devices documentation to validate authenticity before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring robust fault protection against large ground loop voltages. The half-duplex configuration suits bidirectional communication needs. Consider the 250kbps slew-limited mode if electromagnetic interference reduction is critical. Verify that the logic supply voltage aligns with the system's digital interface requirements.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2862 series of low-power RS-485/RS-422 transceivers. It shares pin compatibility with LT1785 and LT1791 devices. The HS designation specifies the extended temperature range variant. The family includes full-duplex options like the LTC2863 and multi-driver variants like the LTC2864.

Drivers, Receivers, Transceivers Replacement Considerations

LT1785 and LT1791 are pin-compatible alternatives within the same product family.
