LTC2879XMS8E#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2879XMS8E#TRPBF is a rugged RS485/RS422 transceiver designed for extreme environments, operating from –55°C to 175°C. It supports data rates up to 20Mbps with a supply voltage range of 3.0V to 5.5V. The device features ±60V fault tolerance on bus pins and ±52kV ESD protection on interface pins. It includes balanced differential receiver thresholds with 240mV hysteresis and full failsafe operation. The component is manufactured using special processing to prevent intermetallic growth at high temperatures and lacks thermal shutdown circuitry.

Drivers, Receivers, Transceivers Feature Summary

• Guaranteed operation across an extended temperature range of –55°C to 175°C with 100% testing at the upper limit.
• Robust electrical protection including ±60V fault tolerance on bus lines and ±52kV ESD protection on interface pins.
• Balanced signal thresholds with 240mV hysteresis to ensure superior noise tolerance and low duty cycle distortion.
• Full failsafe operation ensures receiver output defaults to logic high during open, shorted, or terminated conditions.

Drivers, Receivers, Transceivers Applications

• Oil and gas exploration systems
• High temperature industrial control applications
• PROFIBUS-DP networks
• Military systems
• Harsh environment communications

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging when sourcing this component. Confirm that the MS8E package designation corresponds to the 8-lead plastic MSOP form factor. Ensure the part number matches the Analog Devices Inc. manufacturer specification for the LTC2879X series before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this transceiver for designs requiring reliable communication in high-temperature scenarios exceeding standard industrial limits. The wide common mode input range of ±25V makes it suitable for noisy systems with significant ground potential differences. Verify that the 3V to 5.5V supply compatibility aligns with the system power rails and that the 20Mbps maximum baud rate meets the network speed requirements.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC2879X family of high-temperature RS485/RS422 transceivers. It shares core specifications with variants like the LTC2879XMS8E#PBF but differs in packaging format. The X suffix denotes the extended temperature grade capable of withstanding junction temperatures up to 175°C without thermal shutdown intervention.

Drivers, Receivers, Transceivers Replacement Considerations

The LTC2879XMS8E#PBF serves as a tube-packaged alternative within the same family. No other direct cross-model substitutes are confirmed in the provided documentation.

Drivers, Receivers, Transceivers FAQ

Does the LTC2879X include a thermal shutdown circuit?

No, the device lacks a thermal shutdown circuit to ensure continuous operation at high temperatures.

What is the ESD protection level for the A and B pins?

The interface pins (A and B) are protected to ±52kV Human Body Model when unpowered.

How does the receiver handle failsafe conditions?

The receiver guarantees a logic high output state if inputs are open, shorted, or terminated but undriven for more than approximately 1.5µs.
