LTC2858IMS-1#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2858IMS-1#TRPBF is a low-power, full-duplex RS485/RS422 transceiver manufactured by Analog Devices Inc. It operates on a single 5V supply and supports maximum data rates of 20Mbps. The device features enhanced ESD protection capable of withstanding ±15kV (human body model) without latchup or damage. It includes current-limited drivers and thermal shutdown to prevent excessive power dissipation during bus contention. The receiver guarantees a high output state under floating or shorted input conditions. It is available in a 10-lead MSOP package.

Drivers, Receivers, Transceivers Feature Summary

• Full-duplex communication capability with independent driver and receiver channels
• Enhanced electrostatic discharge protection rated at ±15kV HBM on interface pins
• Guaranteed failsafe receiver operation ensuring a high output state for undriven buses
• Integrated thermal shutdown and current limiting for fault protection

Drivers, Receivers, Transceivers Applications

• Low EMI industrial communication networks
• Backplane transceiver systems
• Level translation interfaces
• Multi-node RS485/RS422 bus systems supporting up to 256 nodes

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #TRPBF confirms tape and reel packaging when sourcing this component. Confirm the IMS-1 designation corresponds to the 10-lead MSOP package and 20Mbps speed grade. Ensure the manufacturer is identified as Analog Devices Inc. for authenticity. Cross-reference the part number against official distributor catalogs to validate availability status prior to procurement.

Drivers, Receivers, Transceivers Selection Notes

Select the LTC2858-1 variant for full-duplex applications requiring 20Mbps data rates. Choose the -I grade for industrial temperature ranges (-40°C to 85°C) or -H grade for extended ranges up to 125°C. The -1 suffix indicates the high-speed version, whereas -2 denotes slew-rate limited 250kbps operation. Ensure the system design accommodates the 900µA maximum receive mode supply current.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC285x family of low-power RS485/RS422 transceivers. It shares architectural similarities with the LTC2856 and LTC2857 series but is distinguished by its full-duplex configuration and dedicated enable controls. The family emphasizes robust fault protection and high node count support within compact surface-mount packages.
