LTC2852CDD#PBF

Drivers, Receivers, Transceivers Overview

The LTC2852CDD#PBF is a low-power, full-duplex RS-485/RS-422 transceiver operating on a 3.3V supply with a maximum data rate of 20Mbps. It features a one-eighth unit load receiver supporting up to 256 nodes per bus and guaranteed failsafe operation for floating or shorted inputs. The device includes current-limited drivers and thermal shutdown protection. Enhanced ESD protection withstands ±15kV (HBM). Typical supply currents are 370µA in receive mode and 450µA in transmit mode. It is housed in an 8-Lead (3mm × 3mm) Plastic DFN package.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm lead-free status and tape-and-reel packaging configuration. Ensure the component matches the required temperature grade and package dimensions before integration into production designs.

Drivers, Receivers, Transceivers Selection Notes

Select this part for applications requiring full-duplex operation at speeds up to 20Mbps with minimal power consumption. The high input impedance allows for extensive network topologies. Verify that the 3.3V supply voltage aligns with system requirements and that the DFN package fits the available PCB footprint.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC285x family of low-power transceivers designed for robust serial communication. It shares core electrical characteristics with the LTC2850 and LTC2851 but provides full-duplex functionality with dedicated enable pins for precise control over transmission and reception states.

Drivers, Receivers, Transceivers FAQ

What is the failsafe behavior of the receiver?

The receiver guarantees a logic-high output state when the inputs are floating, shorted, or terminated but not driven, across the entire common mode range.

How does the device handle driver faults?

The driver outputs are protected by current limiting and thermal shutdown, which disables both the driver and receiver if excessive power dissipation occurs.

What is the typical supply current in receive mode?

The typical supply current in receive mode is 370µA.
