LTC2862AMPS8-1#PBF

Drivers, Receivers, Transceivers Overview

The Analog Devices LTC2862AMPS8-1#PBF is a half-duplex RS-485/RS-422 transceiver operating on a 3V to 5.5V supply. It supports data rates up to 20Mbps with ±60V overvoltage fault protection on interface pins during all modes, including power-down. The device features ±40kV HBM ESD protection and Level 4 IEC ESD/EFT immunity. It operates within an extended temperature range of –55°C to 125°C and utilizes an 8-lead (150mm) Plastic SO package.

Drivers, Receivers, Transceivers Feature Summary

• Provides ±60V overvoltage fault protection on A and B pins across all operational states
• Features robust ESD protection rated at ±40kV HBM and Level 4 IEC standards on interface pins
• Supports high-speed transmission up to 20Mbps or low EMI operation at 250kbps
• Includes enhanced 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
• Medical Equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific MP-grade suffix (MP) ensures the –55°C to 125°C temperature rating required for your application. Confirm the S8 package dimensions match your PCB footprint constraints. Ensure ordering documentation aligns with the #PBF lead-free finish specification before finalizing procurement records.

Drivers, Receivers, Transceivers Selection Notes

Select this part when extreme environmental temperatures below –40°C are expected, as standard grades do not cover –55°C. Choose the -1 variant for maximum throughput requirements up to 20Mbps. Verify that the system ground loop voltages remain within the ±25V common mode input range to ensure reliable communication without signal degradation.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC2862A family, which improves upon the original LTC2862 by adding higher ESD tolerance and noise immunity. The AMPS8 designation specifically identifies the military/industrial grade (-55°C to 125°C) in the small outline package. It serves as a ruggedized interface solution for harsh electrical environments compared to standard commercial variants.

Drivers, Receivers, Transceivers Replacement Considerations

The LTC2862AIS8-1#PBF offers identical functionality but is limited to –40°C to 85°C. The LTC2862AHS8-1#PBF provides –40°C to 125°C coverage. Direct pin-compatible replacements include the non-A version LTC2862IS8-1#PBF, though it lacks the enhanced ESD and failsafe improvements.
