LTC2862MPS8-1#PBF

Drivers, Receivers, Transceivers Overview

The Analog Devices LTC2862MPS8-1#PBF is a half-duplex RS485/RS422 transceiver housed in an 8-lead (150mil) plastic SO package. It operates on a primary supply voltage of 3V to 5.5V and supports data rates 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 ±8kV on other pins. The operating ambient temperature range is –55°C to 125°C.

Drivers, Receivers, Transceivers Feature Summary

• Protected from overvoltage line faults to ±60V
• Extended common mode range of ±25V
• High input impedance supporting up to 256 nodes
• Guaranteed failsafe receiver operation with fully balanced thresholds

• 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 MP-grade suffix against official documentation to confirm military specifications. Ensure the ordering information matches the required temperature range and package type. Confirm lead-free finish compliance and tape-and-reel availability if applicable. Cross-reference the part marking code for accurate identification upon receipt.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring extended industrial temperature ranges and high noise immunity. The half-duplex configuration suits standard RS485 bus topologies. Consider the ±60V fault tolerance for environments with significant ground loop voltages. Verify logic supply compatibility if interfacing with lower voltage digital controllers.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2862/LTC2863/LTC2864/LTC2865 family of low-power transceivers. The MPS8 suffix denotes the MP-grade military specification variant within the 8-lead SOIC package lineup. It shares pinout compatibility with legacy parts like the LT1785 and LT1791 while offering enhanced fault protection.

Drivers, Receivers, Transceivers Replacement Considerations

Publicly confirmed substitutes include other variants within the LTC2862 series such as LTC2862HS8-1#PBF for commercial/high-temp grades, provided the temperature range requirements are met. Direct pin-compatible replacements from other manufacturers require careful verification of electrical characteristics.
