LTC2852IMS#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2852IMS#TRPBF is a 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, thermal shutdown protection, and enhanced ESD protection up to ±15kV HBM. Typical supply currents are 370µA in receive mode and 450µA in transmit mode. It is housed in an 8-pin MSOP package.

Drivers, Receivers, Transceivers Feature Summary

• Full-duplex communication capability with independent driver and receiver channels
• High input impedance receiver design allowing connection of up to 256 nodes on the bus
• Integrated failsafe logic ensuring high output state during input faults or disconnection
• Robust protection against overcurrent, thermal overload, and electrostatic discharge events

Drivers, Receivers, Transceivers Applications

• Low power RS-485/RS-422 transceiver networks
• Level translator circuits
• Backplane transceiver interfaces

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific temperature grade suffix (C, I, H, MP) required for the application environment. Confirm that the IMS8 package designation matches the intended PCB footprint. Ensure the TRPBF suffix indicates tape and reel packaging compatible with automated assembly equipment.

Drivers, Receivers, Transceivers Selection Notes

Select this component when full-duplex operation is necessary alongside low power consumption requirements. The high input impedance makes it suitable for multi-drop networks requiring extensive node counts. Verify that the 3.3V supply voltage aligns with the system architecture before implementation.

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 lies in its duplex configuration and inclusion of dedicated enable pins for precise control of transmission and reception states.

Drivers, Receivers, Transceivers FAQ

What is the receiver input resistance?

The receiver input resistance is greater than 96kΩ for C-grade and I-grade parts, representing a one-eighth unit load.

How does the device handle input faults?

It features a failsafe mechanism that guarantees a high output state when inputs are floating, shorted, or terminated but undriven.

What is the maximum ESD rating?

The device withstands up to ±15kV human body model (HBM) on the interface pins without latchup or damage.
