LTC2852CMS#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2852CMS#TRPBF is a full-duplex RS485/RS422 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 and includes failsafe logic for floating inputs. The device operates within a commercial temperature range of 0°C to 70°C. Typical supply currents are 370µA in receive mode, 450µA in transmit mode, and 5µA maximum in shutdown. Driver outputs provide current limiting and thermal shutdown protection.

Drivers, Receivers, Transceivers Feature Summary

• Full-duplex operation with independent driver and receiver channels
• High input impedance receiver supports up to 256 nodes per bus
• Enhanced ESD protection withstands ±15kV human body model without latchup
• Guaranteed failsafe receiver output under floating or shorted input conditions

Drivers, Receivers, Transceivers Applications

• Low power RS485/RS422 transceivers
• Level translator circuits
• Backplane transceiver applications

Drivers, Receivers, Transceivers Procurement Notes

Verify the component matches the specific package type and temperature grade required for your design. Confirm that the ordering suffix corresponds to the tape and reel packaging format. Ensure compatibility with your system's voltage levels and interface requirements before finalizing procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this part for designs requiring full-duplex communication at speeds up to 20Mbps. It is suitable for systems needing high node density due to its low unit load. Consider the commercial temperature range limits when evaluating environmental constraints. Verify pinout compatibility if replacing legacy components.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC285x family of low-power transceivers from Analog Devices. It shares core electrical characteristics with the half-duplex LTC2850 and the enable-less full-duplex LTC2851. The primary distinction is the inclusion of dedicated driver and receiver enable pins for precise control.

Drivers, Receivers, Transceivers FAQ

What is the typical supply current in shutdown mode?

The typical supply current in shutdown mode is 5µA maximum for the C-grade version.

How does the receiver handle floating inputs?

The receiver includes a failsafe feature that guarantees a high output state when inputs are floating or shorted.

What is the maximum ESD rating for the interface pins?

The parts can withstand up to ±15kV (human body model) on the transceiver interface pins without latchup or damage.
