LTC2864HS-1#PBF

Drivers, Receivers, Transceivers Overview

The LTC2864HS-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 data rates up to 20Mbps. The device features ±60V fault protection on transmission lines, ±15kV ESD protection on interface pins, and an extended common mode range of ±25V. It includes one driver and one receiver with shutdown capability. The component is housed in a 14-lead plastic 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 during all modes of operation
• Enhanced ESD protection allows withstand of ±15kV HBM on interface pins without latchup
• Extended common mode range of ±25V improves reliability in electrically noisy environments
• Guaranteed failsafe receiver operation ensures logic 1 state when inputs are shorted or open

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and temperature grade. Ensure compatibility with system power supplies and logic levels before integration. Confirm RoHS compliance status through authorized distributors. Validate pin configurations against schematic requirements. Check for any recent product change notifications affecting specifications.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring high fault tolerance on RS-422/RS-485 networks. The HS suffix indicates an extended industrial temperature range suitable for harsh environments. Consider the full-duplex architecture if simultaneous bidirectional communication is required. Verify that the 20Mbps data rate meets system bandwidth needs. Evaluate the need for ±60V protection based on potential ground loop voltages in the installation site.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2862/LTC2863/LTC2864/LTC2865 family of low-power transceivers. The LTC2864 variant specifically provides full-duplex operation with separate transmit and receive lines. The 'H' designation denotes the extended temperature grade, while 'S' indicates the SOIC package. These devices share pinout compatibility with legacy parts like the LT1785 and LT1791.

Drivers, Receivers, Transceivers Replacement Considerations

Pin-compatible replacements include the LT1785 and LT1791. Verify electrical parameters such as supply voltage range and data rates when substituting. Ensure the replacement part offers equivalent fault protection levels if operating in high-voltage fault environments.
