LTC2846IG#PBF

Drivers, Receivers, Transceivers Overview

The LTC2846IG#PBF is a multiprotocol transceiver featuring three drivers and three receivers, designed for software-selectable operation across RS-232, RS-449, EIA530, EIA530-A, V.35, V.36, and X.21 protocols. It integrates an on-chip boost switching regulator operating at 1.2MHz to generate 5V from a 3.3V input, powering an internal charge pump that produces VDD and VEE supplies. The device includes automatic cable termination networks and operates within a supply voltage range of 3V to 3.6V for VIN and 4.75V to 5.25V for VCC. It supports data rates up to 10Mb/s in specific modes and functions within an industrial temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Software-selectable multiprotocol support for serial interface standards including RS-232, V.35, and X.21 via mode select pins.
• Integrated boost switching regulator and charge pump eliminate external high-voltage generation components.
• On-chip automatic cable termination adapts to selected protocol without discrete resistor networks.
• Complete DTE or DCE port functionality when combined with companion LTC2844 or LTC2845 devices.

Drivers, Receivers, Transceivers Applications

• Data networking equipment requiring multiprotocol compatibility
• Channel Service Unit/Data Service Unit (CSU/DSU) implementations
• Data routers utilizing standard serial interfaces

Drivers, Receivers, Transceivers Procurement Notes

Verify the component authenticity by checking the manufacturer marking against the official datasheet specifications. Confirm the package type matches the 36-lead SSOP form factor. Ensure the suffix #PBF indicates lead-free compliance as per RoHS directives. Cross-reference the part number with Analog Devices documentation to validate the specific grade and temperature rating.

Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring a single IC to handle multiple serial interface standards without external termination resistors. It is suitable for systems powered by a 3.3V rail that need integrated voltage conversion for RS-232 levels. Consider pairing with LTC2844 or LTC2845 for complete control signal handling. Verify that the 36-lead SSOP package fits the available PCB footprint constraints.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2846 series of multiprotocol transceivers manufactured by Analog Devices. It is specifically the industrial temperature grade variant housed in a plastic SSOP package. The series is designed to simplify serial interface design by integrating power management and termination logic into a single chip, reducing board space and component count compared to traditional discrete solutions.
