LTC2864MPS-1#PBF

Drivers, Receivers, Transceivers Overview

The LTC2864MPS-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 and supports data rates up to 20Mbps or low EMI 250kbps modes. 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 current-limited drivers, thermal shutdown, and guaranteed failsafe receiver operation. This specific variant utilizes a 14-lead (150mil) Plastic SO package and is rated for an operating temperature range of –55°C to 125°C.

Drivers, Receivers, Transceivers Feature Summary

• 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 complete part number including the MPS suffix to confirm the military-grade temperature range and plastic SO package configuration. Ensure compatibility with system voltage requirements between 3V and 5.5V. Confirm that the 14-lead footprint matches the PCB layout specifications. Validate that the application environment does not exceed the absolute maximum ratings for interface voltages.

Drivers, Receivers, Transceivers Selection Notes

Select this component when full-duplex communication is required alongside high fault tolerance. The MPS grade is suitable for harsh environments requiring operation down to –55°C. Consider the 20Mbps rate for high-speed needs or the 250kbps slew-limited mode for reduced electromagnetic interference. Ensure the logic supply aligns with the VCC range as this variant lacks a separate VL pin.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC286x family of ruggedized transceivers designed for industrial applications. It shares pinout and functional similarities with the LTC2863 but provides full-duplex capability unlike the half-duplex LTC2862. The MPS designation indicates a specialized military-grade version within the broader LTC2864 product line, offering extended reliability compared to standard commercial variants.

Drivers, Receivers, Transceivers FAQ

Does the LTC2864MPS-1#PBF have a separate logic supply pin?

No, the LTC2864 does not feature a VL pin; it operates using a single VCC supply ranging from 3V to 5.5V.

What is the maximum data rate supported by this transceiver?

The device supports a maximum data rate of 20Mbps in high-speed mode or 250kbps in the low EMI slew-limited mode.

How does the device handle open or shorted bus lines?

It guarantees failsafe receiver operation, forcing the output to a logic 1 state if the differential input voltage falls below the threshold due to open or shorted lines.
