LTC2855IDE

Drivers, Receivers, Transceivers Overview

The LTC2855IDE is a low-power, full-duplex RS485/RS422 transceiver operating on a 3.3V supply with a maximum data rate of 20Mbps. It features an integrated logic-selectable 120Ω termination resistor and supports up to 256 nodes per bus due to its one-eighth unit load receiver input resistance. The device includes enhanced ESD protection capable of withstanding ±15kV on interface pins without latchup or damage. It operates within a temperature range of -40°C to +85°C and is housed in a 12-lead (4mm × 3mm) plastic DFN package.

Drivers, Receivers, Transceivers Feature Summary

Integrated switchable 120Ω termination resistor controlled by the TE pin
Full-duplex operation with separate driver and receiver channels
Guaranteed failsafe receiver operation ensuring high output during floating or shorted inputs
Thermal shutdown and current-limited drivers protect against excessive power dissipation

Drivers, Receivers, Transceivers Applications

Supervisory Control and Data Acquisition (SCADA)
Industrial control and instrumentation networks
Building automation and security systems

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix to confirm the package type and lead finish. Ensure the temperature grade matches the operational requirements. Confirm RoHS compliance status through official documentation before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring full-duplex communication at speeds up to 20Mbps. The integrated termination simplifies board layout compared to discrete solutions. Verify that the 3.3V supply voltage aligns with system power rails.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2854/LTC2855 family of 3.3V RS485/RS422 transceivers. While the LTC2854 provides half-duplex functionality, the LTC2855 offers full-duplex capability. Both share similar low-power characteristics and integrated termination features.
