LTC2857CMS8-1#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2857CMS8-1#TRPBF is a low-power, full-duplex RS485/RS422 transceiver operating on a 5V supply. It supports maximum data rates of 20Mbps or 250kbps for low EMI applications. The receiver features a one-eighth unit load, supporting up to 256 nodes per bus (C and I-Grade). Enhanced ESD protection withstands ±15kV HBM without latchup. The device includes current-limited drivers and thermal shutdown. Operating temperature range is 0°C to 70°C. Supply current in receive mode is typically 900µA maximum.

Drivers, Receivers, Transceivers Feature Summary

• Full-duplex communication with independent driver and receiver channels
• Enhanced ESD protection rated at ±15kV human body model
• High input impedance receiver supporting up to 256 nodes
• Integrated thermal shutdown and current limiting for fault protection

Drivers, Receivers, Transceivers Applications

• Low power RS485/RS422 transceivers
• Level translators
• Backplane transceivers

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when sourcing this component. Confirm the C grade designation corresponds to the commercial temperature range of 0°C to 70°C for your environmental requirements. Ensure compatibility with standard MSOP-8 footprints during procurement planning.

Drivers, Receivers, Transceivers Selection Notes

Select this part for full-duplex applications requiring high node counts on RS485 or RS422 buses. The C-grade temperature range suits commercial environments. Consider the slew-rate limited variant if lower EMI emissions are critical over maximum speed.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC2857 family of low-power transceivers. It shares architectural similarities with half-duplex variants like the LTC2856 but provides simultaneous transmit and receive capabilities. The MSOP-8 package offers a compact solution for space-constrained designs.
