LTC2864MPS-2#PBF

Drivers, Receivers, Transceivers Overview

The LTC2864MPS-2#PBF is a full-duplex RS485/RS422 transceiver manufactured by Analog Devices Inc. It operates on a 3V to 5.5V supply and features ±60V fault protection on data lines during all modes, including power-down. The device supports a maximum data rate of 250kbps with low EMI characteristics. It provides an extended common mode range of ±25V and includes ±15kV ESD protection on interface pins. The component is housed in a 14-lead plastic SO package and is rated for military-grade operation from –55°C to 125°C.

Drivers, Receivers, Transceivers Feature Summary

• Protected from overvoltage line faults up to ±60V
• Extended common mode input range of ±25V
• Guaranteed failsafe receiver operation
• High input impedance supporting up to 256 nodes

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 MPS indicates the military temperature grade (-55°C to 125°C) and plastic SO package configuration. Confirm that the -2 suffix corresponds to the 250kbps slew-rate limited data rate variant. Ensure compatibility with system voltage requirements between 3V and 5.5V before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when high noise immunity and robust fault protection are required for long-distance industrial communication. The 250kbps data rate suits applications where lower bandwidth reduces electromagnetic interference. Verify that the 14-lead SO package fits the available PCB footprint and thermal constraints for the target operating environment.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2862/LTC2863/LTC2864/LTC2865 family of low-power transceivers. The MPS suffix denotes the military-grade temperature range extension compared to standard commercial or industrial variants. The -2 designation specifies the low-speed 250kbps mode, distinguishing it from the 20Mbps high-speed versions within the same series.

Drivers, Receivers, Transceivers Replacement Considerations

The datasheet notes pin compatibility with LT1785 and LT1791 devices. Verify electrical specifications against these alternatives to ensure adequate fault protection levels and data rate support for the specific application requirements.
