LTC2855HGN#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2855HGN#TRPBF is a full-duplex RS-485/RS-422 transceiver operating on a single 3.3V supply. It supports data rates up to 20Mbps and features an integrated logic-selectable 120Ω termination resistor. The device includes a failsafe receiver that guarantees a high output state during floating or shorted input conditions. It offers enhanced ESD protection of ±15kV on interface pins without latchup. Typical receive mode current is 370µA, with shutdown current at 5µA maximum for the H-grade. It operates within a temperature range of -40°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated switchable 120Ω termination resistor controlled by logic input
• Full-duplex operation with independent driver and receiver channels
• Guaranteed failsafe receiver operation across the entire common mode range
• High input impedance supporting up to 256 nodes per bus

Drivers, Receivers, Transceivers Applications

• Industrial automation networks requiring robust fault protection
• Building automation systems utilizing RS-485 communication protocols
• Process control applications with long cable runs and multiple nodes
• Backplane transceivers in embedded systems

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm the H-grade designation corresponds to the extended industrial temperature range requirements for your specific deployment environment. Ensure compatibility with standard 3.3V logic levels for control signals.

Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring full-duplex communication capabilities rather than half-duplex alternatives like the LTC2854. The integrated termination simplifies board layout compared to external resistor solutions. Verify that the 125°C operating range meets thermal constraints, as lower grade variants offer reduced temperature specifications.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2854/LTC2855 family of low-power RS-485/RS-422 transceivers. It shares core electrical characteristics with the LTC2854 but provides full-duplex functionality through separate transmit and receive lines. The HGN suffix denotes the 16-lead SSOP package variant optimized for higher pin count applications.

Drivers, Receivers, Transceivers Replacement Considerations

LTC2855IGN#TRPBF serves as a direct substitute for applications limited to the -40°C to 85°C temperature range.
