LTC2863MPS8-2#PBF

Drivers, Receivers, Transceivers Overview

The Analog Devices LTC2863MPS8-2#PBF is a full-duplex RS-485/RS-422 transceiver operating on a 3V to 5.5V supply. It supports a maximum data rate of 20Mbps and features ±60V fault protection on transmission lines. The device operates within an extended temperature range of –55°C to +125°C. It includes one driver and one receiver, with a typical supply current of 3.3mA in slew-rate limited mode. The unit is housed in an 8-lead SOIC package.

Drivers, Receivers, Transceivers Feature Summary

• Protected from overvoltage line faults up to ±60V during all operational modes
• Extended common mode input range of ±25V for reliable operation in noisy environments
• Guaranteed failsafe receiver operation ensuring logic high output when inputs are idle
• High input impedance supporting up to 256 nodes on the bus

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 MP-grade temperature rating and package configuration against official manufacturer documentation before procurement. Confirm that the ordering suffix corresponds to the required lead finish and shipping container type. Ensure compatibility with system voltage levels and interface requirements.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring robust fault tolerance and wide operating temperatures. The MPS8 suffix indicates military/extended grade performance suitable for harsh environments. Verify pinout compatibility if replacing legacy parts like the LT1785 or LT1791.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC286x family of low-power, fault-protected transceivers. The MPS8 designation specifically identifies the –55°C to +125°C temperature grade variant packaged in an 8-lead plastic SOIC. It complements lower-grade industrial and commercial options within the same functional series.

Drivers, Receivers, Transceivers Replacement Considerations

Publicly confirmed pin-compatible replacements include the LT1785 and LT1791. Verify that substitute components meet the specific ±60V fault protection and extended temperature requirements of the original design.
