LTC2857HMS8-2#TRPBF

Drivers, Receivers, Transceivers Overview

The Analog Devices LTC2857HMS8-2#TRPBF is a low-power, full-duplex RS485/RS422 transceiver operating on a 5V supply. It supports a maximum data rate of 250kbps with slew rate limiting for low EMI applications. The device features a one-eighth unit load receiver input resistance exceeding 96kΩ, supporting up to 256 nodes per bus. It includes enhanced ±15kV HBM ESD protection, current-limited drivers, and thermal shutdown. The part operates within a temperature range of -40°C to 125°C (H-Grade) and is housed in an 8-lead MSOP package.

Drivers, Receivers, Transceivers Feature Summary

• Full-duplex operation with independent driver and receiver channels
• Slew rate limited output for reduced electromagnetic interference emissions
• High input impedance receiver supporting extensive bus node counts
• Integrated thermal shutdown and current limiting for fault protection

Drivers, Receivers, Transceivers Applications

• Low EMI industrial communication networks
• Backplane transceivers requiring high noise immunity
• Level translation between logic domains and RS485/RS422 buses

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm the H-grade designation matches the required -40°C to 125°C operating temperature range for your application environment. Ensure compatibility with 5V supply rails as specified in the datasheet electrical characteristics.

Drivers, Receivers, Transceivers Selection Notes

Select this model over the LTC2857-1 variant when minimizing electromagnetic interference is critical due to its 250kbps slew-rate limited design. Choose the H-grade version for automotive or harsh environments requiring extended temperature performance. Verify that the full-duplex architecture meets the simultaneous transmit and receive requirements of the system design.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC285x family of low-power RS485/RS422 transceivers. It shares architectural similarities with the half-duplex LTC2856 series but provides independent transmit and receive paths. The device complements the LTC2858 series by offering full-duplex capability without dedicated enable pins for the driver and receiver.
