LTC2851MPMS8#PBF

Drivers, Receivers, Transceivers Overview

The Analog Devices LTC2851MPMS8#PBF is a full-duplex RS-485/RS-422 transceiver operating on a 3.3V supply with a maximum data rate of 20Mbps. It features one-eighth unit load receiver input impedance, supporting up to 256 nodes per bus. The device includes failsafe logic guaranteeing a high output state for floating or shorted inputs. Enhanced ESD protection withstands ±15kV (HBM). It operates within a military temperature range of -55°C to 125°C and is housed in an 8-lead MSOP package.

Drivers, Receivers, Transceivers Feature Summary

• Full-duplex operation with independent driver and receiver channels
• Military-grade extended temperature range capability
• High input impedance allowing extensive multinode network configurations

Drivers, Receivers, Transceivers Applications

• Multinode industrial communication networks
• Harsh environment instrumentation systems
• Backplane transceiver interfaces

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific MP suffix indicates the military temperature grade (-55°C to 125°C) against the official datasheet. Confirm the MS8 package designation matches the required footprint. Ensure the #PBF lead-free designation aligns with environmental compliance requirements for the target assembly process.

Drivers, Receivers, Transceivers Selection Notes

Select this component when simultaneous bidirectional communication is required. The full-duplex architecture differs from half-duplex alternatives like the LTC2850. The MP grade is necessary for applications exceeding standard industrial temperature limits. Verify that the 20Mbps speed meets system timing constraints.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC285x family of low-power transceivers. It shares core electrical characteristics with the LTC2851IS8 but differs in temperature rating and package type. The MP suffix specifically denotes the military qualification level, distinguishing it from commercial or industrial variants within the same functional series.

Drivers, Receivers, Transceivers Replacement Considerations

LTC2851IS8#PBF offers identical electrical performance in an SOIC-8 package with a lower temperature range. LTC2851MPDD#PBF provides the same military grade in a DFN-8 package.
