LTC2858CMS-1#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2858CMS-1#TRPBF is a low power, full-duplex RS485/RS422 transceiver operating on a 5V supply. It supports a maximum data rate of 20Mbps and features enhanced ESD protection capable of withstanding ±15kV (human body model) without latchup or damage. The receiver input resistance exceeds 96kΩ in receive mode, representing a one-eighth unit load that supports up to 256 nodes per bus. It includes current-limited drivers and thermal shutdown for fault protection. The device operates within a commercial temperature range of 0°C to 70°C and is available in a 10-lead MSOP package.

Drivers, Receivers, Transceivers Feature Summary

• Full-duplex operation with independent driver and receiver control
• High input impedance supporting up to 256 nodes on the bus
• Enhanced ESD protection rated at ±15kV HBM on interface pins
• Guaranteed failsafe receiver operation ensuring high output state during floating inputs

Drivers, Receivers, Transceivers Applications

• Low power RS485/RS422 communication networks
• Level translation between different voltage domains
• Backplane transceiver applications requiring high node density

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm the CMS8 designation corresponds to the correct 10-lead MSOP package variant required for your PCB layout. Ensure the C grade matches the commercial temperature requirements of your design environment.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring full-duplex communication with high noise immunity and low static power consumption. The 20Mbps data rate suits high-speed industrial protocols, while the one-eighth unit load allows for extensive network topologies. Verify that the 5V supply voltage aligns with your system's power architecture.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC285x family of low power RS485/RS422 transceivers from Analog Devices. It shares core electrical characteristics 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 capacity for demanding serial communication environments.

Drivers, Receivers, Transceivers Replacement Considerations

LTC2858IMS-1#PBF offers identical electrical specifications in a 10-lead MSOP tube package instead of tape and reel. LTC2858HDD-1#PBF provides the same functionality in a 10-lead DFN package. Both alternatives maintain the 20Mbps data rate and 15kV ESD protection capabilities.
