LTC2855CGN#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2855CGN#TRPBF is a 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 impedance. The device includes failsafe circuitry guaranteeing a high output state during floating or shorted inputs, along with current-limited drivers and thermal shutdown protection. It operates within a temperature range of 0°C to 70°C and is housed in a 16-lead SSOP 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
• High input impedance supporting up to 256 nodes on the bus
• Failsafe receiver guarantees a high output state under fault conditions

Drivers, Receivers, Transceivers Applications

• Industrial automation networks requiring RS485/RS422 communication
• Building automation systems utilizing multi-drop bus topologies
• Process control instrumentation with long-distance signal transmission needs

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #TRPBF confirms tape and reel packaging for automated assembly processes. Confirm the CGN designation matches the required 16-lead SSOP package and commercial temperature grade. Ensure the component source provides valid traceability documentation consistent with Analog Devices manufacturing standards.

Drivers, Receivers, Transceivers Selection Notes

Select this model when full-duplex communication is required alongside integrated line termination capabilities. The 16-lead SSOP package offers a suitable footprint for designs prioritizing board space efficiency over the smaller DFN options. Verify that the 3.3V supply voltage aligns with the system power architecture before implementation.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC2854/LTC2855 family of low-power transceivers. While the LTC2854 provides half-duplex functionality, the LTC2855 variant specifically delivers full-duplex performance. Both share identical electrical characteristics regarding termination, failsafe operation, and power consumption profiles.

Drivers, Receivers, Transceivers Replacement Considerations

Direct functional equivalents include the LTC2854 series for half-duplex applications or other models within the same product family sharing the SSOP-16 package and 3.3V operation.
