LTC2854HDD#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2854HDD#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 enhanced ESD protection rated at ±25kV (HBM), current-limited drivers, and thermal shutdown for fault protection. It operates within a temperature range of -40°C to +125°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
• One-eighth unit load receiver input impedance supporting high node counts
• Enhanced ESD protection up to ±25kV HBM without latchup
• Guaranteed failsafe receiver operation under floating or shorted input conditions

Drivers, Receivers, Transceivers Applications

• Industrial automation networks requiring robust fault protection
• Building automation systems utilizing RS-485/RS-422 protocols
• Backplane communication interfaces in embedded systems
• Level translation between different voltage domains in serial communication

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #TRPBF confirms tape and reel packaging when sourcing. Confirm the H-grade designation matches the required -40°C to +125°C operating temperature range for your application environment. Ensure the DD package footprint aligns with your PCB layout constraints before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring integrated line termination to simplify board design. The half-duplex configuration suits bidirectional communication needs. Verify that the 3.3V supply voltage aligns with your system's power rails. Consider the 20Mbps data rate limit against your network speed requirements.

Drivers, Receivers, Transceivers Part Context

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

Drivers, Receivers, Transceivers Replacement Considerations

Public confirmed substitutes include the LTC2855HDE#TRPBF for full-duplex applications and the LTC2854IDD#TRPBF for commercial grade temperature ranges.
