LTC2863HS8-1#PBF

Drivers, Receivers, Transceivers Overview

The LTC2863HS8-1#PBF is a full-duplex RS-422/RS-485 transceiver manufactured by Analog Devices. It operates on a 3V to 5.5V supply voltage and supports data rates up to 20Mbps. The device features ±60V fault protection on interface pins during all modes, including power-down. It provides an extended common mode range of ±25V and ±15kV ESD protection on interface pins. The component is housed in an 8-lead SOIC package and is rated for operation from -40°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• Protected from overvoltage line faults to ±60V
• Extended common mode range of ±25V
• Guaranteed failsafe receiver operation with fully balanced thresholds

Drivers, Receivers, Transceivers Applications

• Supervisory Control and Data Acquisition (SCADA)
• Industrial control and instrumentation networks
• Automotive and transportation electronics

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'H' indicates the industrial temperature grade (-40°C to +125°C) and 'S8' denotes the SOIC-8 package. Confirm the '#PBF' designation ensures lead-free compliance. Cross-reference the manufacturer part number against official Analog Devices documentation to ensure authenticity before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this model for applications requiring full-duplex communication with high noise immunity. The HS variant is appropriate for environments exceeding standard commercial temperature limits. Ensure the system design accommodates the 3V to 5.5V supply range and utilizes the ±60V fault tolerance for robust network reliability.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC286x family of low-power RS-485/RS-422 transceivers. It shares pin compatibility with legacy parts like the LT1785 and LT1791. The 'H' suffix distinguishes it from commercial (C) and industrial (I) grades by offering an extended operating temperature range suitable for harsh conditions.

Drivers, Receivers, Transceivers FAQ

Does the LTC2863HS8-1#PBF support half-duplex operation?

No, the LTC2863 series is designed specifically for full-duplex communication. Half-duplex variants are available within the LTC2862 series.

What is the maximum data rate for this transceiver?

The maximum data rate is 20Mbps. Lower speed options exist in other models within the family, such as the 250kbps versions.

How does the device handle open or shorted input lines?

It features guaranteed failsafe receiver operation that forces the output to a logic 1 state if the differential input voltage is below the threshold for more than approximately 3µs.
