LTC2847IUHF#PBF

Drivers, Receivers, Transceivers Overview

The LTC2847IUHF#PBF is a multiprotocol transceiver with integrated cable termination, housed in a 38-lead QFN package. It operates from a single 5V supply (4.75V to 5.25V) and features a separate digital interface supply (VIN) supporting 3V to 5.25V logic levels. The device includes three drivers and three receivers, generating internal VDD and VEE supplies via an on-chip charge pump. It supports RS232, RS449, EIA530, EIA530-A, V.35, V.36, and X.21 protocols through software-selectable mode pins.

Drivers, Receivers, Transceivers Feature Summary

• Software-selectable multiprotocol support for serial communication standards
• Integrated on-chip cable termination eliminating external resistor networks
• Separate VIN pin enabling compatibility with 3V or 5V digital interfaces
• Internal charge pump generates required positive and negative voltage rails

Drivers, Receivers, Transceivers Applications

• Data networking equipment ports
• Channel Service Unit/Service Delivery Unit (CSU/DSU)
• Data routers requiring DTE or DCE interface flexibility

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance when sourcing. Confirm the IUHF designation corresponds to the industrial temperature range of -40°C to +85°C. Ensure the QFN-38 footprint matches the PCB layout requirements before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a complete DTE or DCE port solution is required without discrete termination components. Pair with the LTC2845 for full control signal handling. Verify that the system requires software-selectable protocol switching rather than fixed hardware configuration.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2847 series of multiprotocol transceivers. It is designed to work in conjunction with companion chips like the LTC2845 to form complete interface ports. The device simplifies design by integrating termination networks previously handled by relays or custom cables.
