LTC2852MPMS#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2852MPMS#TRPBF is a full-duplex RS-485/RS-422 transceiver operating on a 3.3V supply with a maximum data rate of 20Mbps. It features a one-eighth unit load receiver supporting up to 256 nodes per bus and guaranteed failsafe operation for floating or shorted inputs. The device includes current-limited drivers, thermal shutdown protection, and enhanced ESD protection rated at ±15kV HBM. It operates within a military temperature range of -55°C to +125°C and draws a typical supply current of 370µA in receive mode.

Drivers, Receivers, Transceivers Feature Summary

• Full-duplex architecture with independent driver and receiver channels
• High input impedance receiver supports extensive multinode networks
• Integrated overcurrent and thermal protection mechanisms
• Robust interface pins withstand high electrostatic discharge events

Drivers, Receivers, Transceivers Applications

• Multinode industrial communication networks
• Backplane data transmission systems
• Level translation between logic domains

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific MP suffix indicates the military temperature grade (-55°C to +125°C) against the official Analog Devices datasheet. Confirm the MS package designation corresponds to the 8-lead MSOP form factor. Ensure the TRPBF suffix aligns with tape and reel packaging requirements for automated assembly processes.

Drivers, Receivers, Transceivers Selection Notes

Select this component when full-duplex capability is required alongside extreme temperature resilience. The high input impedance allows for dense node configurations exceeding standard RS-485 limits. Verify that the 3.3V supply voltage matches the system power rails and that the 20Mbps speed meets the application bandwidth needs.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC285x family of low-power transceivers designed for robust serial communication. It complements half-duplex variants like the LTC2850 by providing simultaneous transmit and receive paths. The MP grade extends the operational reliability beyond commercial and industrial ranges into demanding environments.

Drivers, Receivers, Transceivers Replacement Considerations

LTC2852IMS#TRPBF offers identical electrical performance but operates within the industrial temperature range (-40°C to +85°C). Substitution requires verification that the reduced temperature rating satisfies the environmental constraints of the target application.
