LTC2862MPS8-2#TRPBF

Drivers, Receivers, Transceivers Overview

The Analog Devices LTC2862MPS8-2#TRPBF is a half-duplex RS-485/RS-422 transceiver in an 8-lead SOIC package. It operates on a 3V to 5.5V supply with a maximum data rate of 250kbps. The device features ±60V overvoltage fault protection on interface pins and ±15kV ESD protection. It supports an extended common mode range of ±25V, includes thermal shutdown, and functions within a –55°C to +125°C temperature range.

Drivers, Receivers, Transceivers Feature Summary

• Provides ±60V overvoltage fault protection on transmission lines during all operational modes
• Features enhanced ESD protection rated at ±15kV HBM on interface pins
• Supports extended common mode input voltage range of ±25V for noisy environments
• Includes guaranteed failsafe receiver operation when inputs are shorted or open

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging rather than tube packaging. Confirm the MPS8 designation corresponds to the military-grade temperature range of –55°C to +125°C. Ensure the ordering information matches the required lead-free finish and package dimensions for your PCB layout.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring robust fault tolerance against high voltage line faults. The 250kbps slew-rate limited mode is suitable for reducing electromagnetic interference compared to higher speed variants. Verify that the half-duplex configuration aligns with the bidirectional communication requirements of the target network topology.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2862 series of low-power RS-485/RS-422 transceivers. It is pin-compatible with legacy parts like the LT1785 and LT1791. The MPS8 variant specifically denotes the extended industrial/military temperature grade available in the plastic SOIC package format.
