LTC2862AHS8-2#PBF

Drivers, Receivers, Transceivers Overview

The Analog Devices LTC2862AHS8-2#PBF is a half-duplex RS-485/RS-422 transceiver housed in an 8-lead SOIC package. It operates on a 3V to 5.5V supply and supports data rates up to 250kbps with slew-rate limiting for low EMI. The device features ±60V overvoltage fault protection on interface pins during all modes, including power-down. It provides Level 4 IEC ESD protection and ±40kV HBM protection on A/B pins. The extended common mode range spans ±25V, ensuring reliable operation in electrically noisy environments.

Drivers, Receivers, Transceivers Feature Summary

• Integrated ±60V overvoltage fault protection on interface pins across all operational states
• Robust electrostatic discharge immunity meeting Level 4 IEC standards and ±40kV HBM ratings
• Extended common mode input range of ±25V for high noise tolerance
• Guaranteed failsafe receiver operation with fully balanced differential thresholds

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 HS8-2#PBF against the manufacturer's current ordering information to confirm the -40°C to +125°C temperature grade and lead-free finish. Ensure the component matches the required automotive or industrial reliability specifications if applicable. Cross-reference the datasheet revision to validate electrical characteristics before final integration.

Drivers, Receivers, Transceivers Selection Notes

Select this variant for applications requiring extended industrial temperature ranges (-40°C to +125°C). The '2' suffix indicates the 250kbps slew-rate limited option suitable for low EMI requirements. Compare against the standard LTC2862 series if higher speed (20Mbps) is needed, or if lower cost commercial grades suffice for non-critical environments.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC2862A family of robust RS-485/RS-422 transceivers. It improves upon the original LTC2862 by offering enhanced ESD protection and optimized failsafe functions. The HS8-2 designation specifically denotes the high-temperature grade within the SOIC-8 package configuration.

Drivers, Receivers, Transceivers Replacement Considerations

The LTC2862AHS8-2#PBF is pin-compatible with the standard LTC2862HS8-2#PBF and the LT1785. Verify that substitute components support the same ±60V fault protection and extended common mode range to maintain system robustness.
