LTC2864CS-1#PBF

Drivers, Receivers, Transceivers Overview

The LTC2864CS-1#PBF is a full-duplex RS-422/RS-485 transceiver manufactured by Analog Devices Inc. It operates on a 3V to 5.5V supply voltage and supports a maximum data rate of 20Mbps. The device features ±60V fault protection on the transmission lines, an extended common mode range of ±25V, and ±15kV ESD protection on interface pins. It includes one driver and one receiver within a 14-lead plastic SO package. The component is rated for commercial operating temperatures from 0°C to +70°C.

Drivers, Receivers, Transceivers Feature Summary

• Provides ±60V overvoltage fault protection on data lines during all operational modes
• Features fully balanced differential receiver thresholds for low duty cycle distortion
• Includes current limited drivers and thermal shutdown protection

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 'CS' indicates the commercial temperature grade (0°C to +70°C) and the 'S' package type against official manufacturer documentation. Confirm that the '#PBF' designation corresponds to lead-free finish requirements. Ensure compatibility with system power supplies between 3V and 5.5V before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this model when full-duplex communication is required alongside high-speed data rates up to 20Mbps. The CS suffix denotes the commercial temperature range; choose IS or HS suffixes if industrial (-40°C to +85°C) or extended (-40°C to +125°C) ranges are necessary. Verify pinout compatibility with legacy LT1785 or LT1791 designs if migrating existing circuits.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC286x family of ruggedized transceivers designed for harsh electrical environments. It shares core architectural features with the LTC2862, LTC2863, and LTC2865 models but is distinct in its full-duplex configuration and lack of a separate logic supply pin found in the LTC2865.

Drivers, Receivers, Transceivers Replacement Considerations

Publicly confirmed pin-compatible replacements include the LT1785 and LT1791. When substituting, verify that the replacement part meets the ±60V fault protection requirement, as standard RS-485 transceivers typically offer significantly lower tolerance.
