LTC2851IDD#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2851IDD#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 enhanced ESD protection up to ±15kV HBM and supports up to 256 nodes via high input impedance (one-eighth unit load). The device includes current-limited drivers, thermal shutdown, and guaranteed failsafe receiver operation across the entire common mode range. Typical supply current is 370µA in receive mode and 450µA in transmit mode.

Drivers, Receivers, Transceivers Feature Summary

• Full-duplex architecture providing simultaneous transmission and reception without enable pins
• High input impedance receiver supporting up to 256 nodes per bus line
• Integrated thermal shutdown and current limiting for driver fault protection
• Guaranteed logic-high output state under floating or shorted input conditions

Drivers, Receivers, Transceivers Applications

• Low power RS-485/RS-422 multinode network interfaces
• Level translation between different voltage domains
• Backplane communication systems requiring high node density

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific temperature grade suffix 'I' corresponds to the industrial range (-40°C to 85°C) required for your application environment. Confirm that the MSOP-8 package variant matches your PCB footprint constraints and soldering profile capabilities before finalizing orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when full-duplex communication is necessary within a 3.3V system. It is suitable for applications demanding high noise immunity and robust fault protection. Ensure the design accounts for the lack of dedicated enable pins compared to half-duplex variants like the LTC2850.

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 but differs in its full-duplex topology. The 'IDD' designation indicates an 8-lead DFN package with industrial temperature rating, while '#TRPBF' specifies tape-and-reel packaging with lead-free composition.

Drivers, Receivers, Transceivers Replacement Considerations

LTC2850IS8#PBF offers similar electrical performance but operates in half-duplex mode with enable pins.
