LTC2852MPMS#PBF

Drivers, Receivers, Transceivers Overview

The Analog Devices LTC2852MPMS#PBF is a low-power, full-duplex RS485/RS422 transceiver operating on a 3.3V supply. It supports a maximum data rate of 20Mbps and features a one-eighth unit load receiver input resistance exceeding 96kΩ, enabling up to 256 nodes per bus for C- and I-grade devices. The component includes current-limited drivers with thermal shutdown protection and enhanced ESD protection rated at ±15kV (human body model). It operates within a military temperature range of –55°C to 125°C and is housed in an 8-pin MSOP package.

Drivers, Receivers, Transceivers Feature Summary

• Full-duplex operation with independent driver and receiver channels
• High input impedance supporting up to 256 nodes per bus
• Guaranteed failsafe receiver output under floating or shorted input conditions
• Current-limited outputs and thermal shutdown for fault protection

Drivers, Receivers, Transceivers Applications

• Low power RS485/RS422 transceivers
• Level translator circuits
• Backplane transceivers

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #PBF indicates lead-free construction and tape and reel packaging configuration. Confirm that the MP suffix corresponds to the required military temperature grade (-55°C to 125°C) for your application environment. Ensure compatibility with the 8-lead MSOP physical footprint during procurement validation.

Drivers, Receivers, Transceivers Selection Notes

Select this part when full-duplex communication is required alongside high node density capabilities. The LTC2852 provides independent transmit and receive paths unlike the half-duplex LTC2850. Verify that the 3.3V supply voltage aligns with system requirements and that the 20Mbps data rate meets transmission speed needs.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC285x family of low-power interface ICs from Analog Devices. It shares core electrical characteristics with the LTC2850 and LTC2851 but distinguishes itself through full-duplex architecture. The MP designation specifically denotes the extended military temperature range variant within this product line.
