LTC2847IUHF#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2847IUHF#TRPBF is a multiprotocol transceiver featuring three drivers and three receivers with integrated cable termination. It supports RS-232, RS-449, EIA530, EIA530-A, V.35, V.36, and X.21 protocols via software-selectable mode pins. The device operates from a single 5V supply (4.75V to 5.25V) for the analog section and a separate digital interface supply (VIN) ranging from 3V to 5.25V. It includes an internal charge pump generating approximately +8V and -7.5V using five external capacitors. The component is housed in a 38-lead 5mm x 7mm QFN package and functions within an industrial temperature range of –40°C to 85°C.

Drivers, Receivers, Transceivers Feature Summary

• Software-selectable multiprotocol support for RS-232, RS-449, EIA530, EIA530-A, V.35, V.36, and X.21 interfaces
• Integrated on-chip cable termination eliminating discrete resistor networks
• Separate VIN supply pin enabling compatibility with 3V or 5V logic levels
• Internal charge pump requiring only five surface-mounted capacitors

Drivers, Receivers, Transceivers Applications

• Data networking equipment
• Channel Service Unit / Data Service Unit (CSU/DSU)
• Data routers

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when sourcing components. Confirm that the IUHF designation corresponds to the industrial temperature grade (-40°C to 85°C). Ensure the ordering information matches the exact manufacturer part number to avoid confusion with non-reel variants or commercial temperature grades.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing a compact serial interface port requiring support for multiple legacy standards without external termination resistors. The separate VIN supply is critical for interfacing with low-voltage ASICs while maintaining standard 5V driver operation. Ensure sufficient decoupling capacitance is placed near the charge pump pins to maintain stability.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2847 family of multiprotocol transceivers. It is designed to work in conjunction with the LTC2845 control signal generator to form a complete DTE or DCE interface port. The combination allows for flexible configuration of data and control lines across various serial communication standards.
