LTC2864HS-2#PBF

Drivers, Receivers, Transceivers Overview

The LTC2864HS-2#PBF is a full-duplex RS-485/RS-422 transceiver from Analog Devices, operating on a 3V to 5.5V supply with a maximum data rate of 250kbps. It features ±60V fault protection on transmission lines and an extended common mode range of ±25V. The device includes enhanced ESD protection rated at ±15kV on interface pins and guarantees failsafe receiver operation. Packaged in a 14-lead plastic SOIC, it supports high input impedance for up to 256 nodes and incorporates current-limited drivers with thermal shutdown.

Drivers, Receivers, Transceivers Feature Summary

• Protected from overvoltage line faults to ±60V during all modes of operation
• Extended common mode range of ±25V for reliable communication in noisy environments
• Enhanced ESD protection with ±15kV rating on interface pins without latchup
• Guaranteed 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 and lighting control

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix HS-2 against official documentation to confirm the industrial temperature grade and slew-rate limited data rate. Ensure the 14-lead SOIC package matches the target PCB footprint. Confirm RoHS compliance status through the manufacturer's latest material declaration before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when full-duplex communication is required alongside robust fault tolerance. The 250kbps low EMI mode is suitable for noise-sensitive applications where higher speeds are unnecessary. Verify that the ±25V common mode range meets the ground loop requirements of the specific installation environment.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC286x family of ruggedized transceivers designed for harsh industrial environments. It shares pin compatibility with legacy parts like the LT1785 and LT1791, facilitating direct upgrades. The HS suffix denotes the extended temperature range variant within the standard plastic SOIC package lineup.

Drivers, Receivers, Transceivers Replacement Considerations

LTC2864IS-2#PBF offers identical electrical performance but operates within a lower commercial temperature range (-40°C to 85°C). Substitution requires verification that the ambient operating conditions do not exceed the IS grade limits.
