LTC2851IMS8#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2851IMS8#TRPBF is a full-duplex RS-485/RS-422 transceiver manufactured by Analog Devices Inc. It operates on a single 3V to 3.6V supply and supports data rates up to 20Mbps. The device features a one-eighth unit load receiver input resistance exceeding 96kΩ, enabling support for up to 256 nodes per bus in C-grade and I-grade configurations. It includes guaranteed failsafe operation ensuring a high output state during floating or shorted inputs. The component provides enhanced ESD protection of ±15kV (HBM) and incorporates current-limited drivers with thermal shutdown. It is housed in an 8-lead MSOP package.

Drivers, Receivers, Transceivers Feature Summary

• Full-duplex architecture with independent driver and receiver channels
• High input impedance supporting up to 256 nodes per bus
• Guaranteed failsafe receiver operation under fault conditions
• Enhanced ESD protection up to ±15kV HBM without latchup

Drivers, Receivers, Transceivers Applications

• Low power RS-485/RS-422 communication networks
• Level translation interfaces
• Backplane transceivers

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #TRPBF confirms tape and reel packaging and lead-free composition. Confirm the IMS8 designation matches the required 8-lead MSOP package and temperature grade. Cross-reference the manufacturer part number with official Analog Devices documentation to ensure authenticity and correct revision status before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when full-duplex communication is required alongside low power consumption. The high input impedance makes it suitable for multi-drop networks requiring many nodes. Ensure the application environment falls within the specified operating temperature range for the I-grade variant. Verify that the 20Mbps maximum data rate meets system timing requirements.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC285x family of low power transceivers. The LTC2851 specifically denotes the full-duplex variant without separate enable pins, distinguishing it from the half-duplex LTC2850 and the enabled full-duplex LTC2852. All variants share similar electrical characteristics regarding speed, voltage, and protection features.
