LTC2854CDD#TRPBF

Drivers, Receivers, Transceivers Overview

The Analog Devices LTC2854CDD#TRPBF is a low-power, half-duplex RS-485/RS-422 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 input impedance. The device includes failsafe receiver operation, current-limited drivers, and thermal shutdown protection. Enhanced ESD protection withstands ±25kV (HBM). It operates within a temperature range of 0°C to 70°C and is housed in a 10-lead 3mm × 3mm DFN package.

Drivers, Receivers, Transceivers Feature Summary

• Integrated switchable 120Ω termination resistor controlled by the TE pin
• High input impedance supporting up to 256 nodes on the bus
• Guaranteed failsafe receiver output state under floating or shorted input conditions
• Enhanced ESD protection rated at ±25kV human body model

Drivers, Receivers, Transceivers Applications

• Low power RS-485/RS-422 communication networks
• Level translator applications
• Backplane transceiver systems

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging when sourcing this component. Confirm the C-grade designation corresponds to the required commercial operating temperature range of 0°C to 70°C for your application environment. Ensure compatibility with the 10-lead DFN footprint during procurement planning.

Drivers, Receivers, Transceivers Selection Notes

Select the LTC2854 variant specifically for half-duplex applications requiring a single differential pair. Consider the H-grade version if operation beyond 70°C is necessary. Verify that the integrated termination meets system impedance requirements before opting for external resistors. Check ESD sensitivity requirements against the ±25kV rating provided.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC2854/LTC2855 family of 3.3V transceivers. The LTC2854 provides half-duplex functionality, whereas the LTC2855 offers full-duplex capability. Both share similar electrical characteristics and protection features but differ in driver output configurations and package availability.
