LTC2862AHS8-1#PBF

Drivers, Receivers, Transceivers Overview

The LTC2862AHS8-1#PBF is a half-duplex RS-485/RS-422 transceiver in an 8-lead SOIC package. It operates on a 3V to 5.5V supply and supports data rates up to 20Mbps. The device features ±60V overvoltage fault protection on interface pins during all modes, including power-down. It provides ±40kV HBM ESD protection on A/B pins and Level 4 IEC ESD/EFT immunity. The extended common mode range spans ±25V with guaranteed failsafe receiver operation. Operating temperature ranges from -40°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• Robust ±60V overvoltage fault protection on interface pins across all operational states
• High-level electromagnetic interference resistance with Level 4 IEC ESD and EFT protection
• Extended common mode input range of ±25V for reliable communication under large ground loop voltages
• Guaranteed failsafe receiver operation ensuring logic high output when inputs are open or shorted

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 HS8-1 against the official Analog Devices datasheet to confirm the industrial/high-temperature grade (-40°C to 125°C) and SOIC-8 package type. Ensure the ordering information matches the lead-free finish designation #PBF. Cross-reference the manufacturer part number directly with authorized distributors to avoid counterfeit components.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring high-speed 20Mbps transmission alongside extreme electrical robustness. The HS8-1 variant is appropriate for environments exceeding standard commercial temperature limits. Consider the LTC2862A-2 option if lower EMI emissions at reduced speeds are required instead of maximum throughput.

Drivers, Receivers, Transceivers Part Context

This device belongs to the LTC2862A family of low-power transceivers designed for harsh industrial environments. It improves upon previous generations by integrating enhanced ESD protection and improved receiver noise immunity. The part is pin-compatible with the original LTC2862 and LT1785, facilitating direct upgrades in existing designs.
