LTC2852CDD#TRPBF

Drivers, Receivers, Transceivers Overview

The Analog Devices LTC2852CDD#TRPBF is a low-power, full-duplex RS485/RS422 transceiver operating on a 3.3V supply. It features a maximum data rate of 20Mbps and supports up to 256 nodes per bus due to its one-eighth unit load receiver input resistance exceeding 96kΩ. The device includes enhanced ESD protection rated at ±15kV (HBM), current-limited drivers, and thermal shutdown. It operates within a commercial temperature range of 0°C to 70°C and is housed in an 8-lead (3mm × 3mm) plastic DFN package with an exposed ground pad.

Drivers, Receivers, Transceivers Feature Summary

• Full-duplex operation with independent driver and receiver channels
• High input impedance supporting up to 256 nodes on the bus
• Integrated failsafe mechanism ensuring high output state during idle or fault conditions
• Robust protection against short circuits, overcurrent, and excessive power dissipation

Drivers, Receivers, Transceivers Applications

• Multinode industrial communication networks
• Backplane transceiver interfaces
• Level translation between logic domains
• Low power RS485/RS422 serial communication links

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #TRPBF confirms tape and reel packaging and lead-free composition. Confirm the C-grade designation matches the required commercial temperature range of 0°C to 70°C for your application environment. Ensure the DFN package footprint aligns with your PCB layout constraints.

Drivers, Receivers, Transceivers Selection Notes

Select this component when full-duplex communication is required alongside low static power consumption. The high input impedance makes it suitable for large multinode networks requiring support for up to 256 devices. Consider the exposed pad requirement for thermal management and grounding in the DFN package design.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC285x family of low-power transceivers. It shares core electrical characteristics with the half-duplex LTC2850 and the enable-less full-duplex LTC2851. The primary distinction is the inclusion of separate Receiver Enable (RE) and Driver Enable (DE) pins for controlled operation.

Drivers, Receivers, Transceivers Replacement Considerations

LTC2852MS#TRPBF offers the same functionality in a 10-lead MSOP package. LTC2852S#TRPBF provides the same specifications in a 14-lead SOIC package. Verify pinout compatibility before substituting different package types.
