LTC2847CUHF#PBF

Drivers, Receivers, Transceivers Overview

The LTC2847CUHF#PBF is a multiprotocol transceiver featuring three drivers and three receivers with integrated cable termination. It operates from a single 5V supply (VCC range: 4.75V to 5.25V) and supports a separate digital interface supply (VIN range: 3V to 5.25V). The device includes an internal charge pump generating approximately +9V and -6V supplies. It supports RS-232, RS-449, EIA530, EIA530-A, V.35, V.36, and X.21 protocols via software-selectable mode pins. The component is housed in a 38-lead 5mm x 7mm QFN package and functions within a commercial temperature range of 0°C to 70°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 standards
• Integrated on-chip cable termination eliminating the need for discrete resistors or relays
• Separate VIN supply pin allowing compatibility with 3V or 5V logic interfaces
• Internal capacitive charge pump generates required positive and negative voltage rails

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 'CUHF' corresponds to the commercial temperature grade (0°C to 70°C) and the 38-lead QFN package configuration. Confirm that the '#PBF' designation indicates lead-free compliance and RoHS adherence as per manufacturer specifications before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a complete DTE or DCE port solution is required without external termination components. Ensure the application utilizes a 5V main supply and requires support for multiple serial protocols including V.35 and RS-232. Verify that the 38-pin QFN footprint fits the PCB layout constraints and that the operating environment remains within the commercial temperature limits.

Drivers, Receivers, Transceivers Part Context

This part belongs to the Analog Devices LTC284x series of multiprotocol transceivers. It is designed to work in conjunction with companion chips like the LTC2845 to form a complete interface port. The CUHF variant specifically denotes the commercial temperature range and the plastic QFN package style.
