LTC2858HMS-2#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2858HMS-2#TRPBF is a low-power, full-duplex RS485/RS422 transceiver manufactured by Analog Devices Inc. It operates on a single 5V supply and supports a maximum data rate of 250kbps with slew-rate limiting to minimize electromagnetic interference (EMI). The device features a one-eighth unit load receiver input impedance, enabling support for up to 256 nodes per bus. It includes enhanced ESD protection rated at ±15kV HBM, current-limited drivers, and thermal shutdown capabilities. The component is housed in a 10-lead MSOP package.

Drivers, Receivers, Transceivers Feature Summary

• Slew-rate limited driver outputs reduce high-frequency EMI emissions and mitigate transmission line termination issues.
• High input impedance receiver design allows connection of up to 256 nodes on the bus without exceeding standard loading limits.
• Integrated failsafe mechanism guarantees a logic-high output state when inputs are floating or shorted.
• Robust protection against excessive power dissipation through current limiting and thermal shutdown.

Drivers, Receivers, Transceivers Applications

• Low EMI industrial communication networks
• Backplane transceiver systems
• Level translation interfaces

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #TRPBF confirms tape and reel packaging rather than tube packaging. Confirm the temperature grade corresponds to the required operational range. Ensure the manufacturer designation matches Analog Devices Inc. specifications before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this model for applications requiring full-duplex communication with strict EMI constraints. The 250kbps data rate suits slower, noise-sensitive environments. Verify that the 10-lead MSOP package fits the board layout constraints compared to the 8-lead alternatives.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC2858 family of low-power RS485/RS422 transceivers. It shares architectural similarities with the LTC2856 and LTC2857 series but is distinct in its full-duplex configuration and 10-lead MSOP package format. The -2 suffix specifically denotes the slew-rate limited variant optimized for low EMI performance.

Drivers, Receivers, Transceivers Replacement Considerations

LTC2858HMS-2#PBF offers identical electrical characteristics but utilizes tube packaging instead of tape and reel.
