LTC2870CFE

Drivers, Receivers, Transceivers Overview

The LTC2870CFE is a robust, pin-configurable multiprotocol transceiver supporting RS-232, RS-485, and RS-422 standards. It operates on a single 3V to 5.5V supply and integrates termination resistors for RS-485/RS-422 buses. The device features fail-safe receivers that ensure a high logic state when inputs are open or shorted. It includes integrated ESD protection rated at ±15kV HBM and supports data rates up to 25Mbps. The component is housed in a 16-lead SSOP package.

Drivers, Receivers, Transceivers Feature Summary

• Integrated bus termination resistors simplify board layout and reduce component count.
• Pin-configurable architecture allows selection between RS-232, RS-485, and RS-422 protocols without hardware changes.
• Fail-safe receiver design maintains a high output state during input disconnection or shorting events.

Drivers, Receivers, Transceivers Applications

• Industrial automation control systems requiring multi-protocol serial communication.
• Building automation networks utilizing RS-485 or RS-422 bus topologies.
• Medical equipment interfaces needing isolated or protected serial data links.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'CFE' against the manufacturer's current datasheet to confirm package type and temperature range. Ensure ordering documentation matches the exact part number to avoid confusion with similar variants like LTC2870CUFD. Cross-reference RoHS compliance status with the latest manufacturing declarations.

Drivers, Receivers, Transceivers Selection Notes

Select this component when system design requires flexibility between RS-232, RS-485, and RS-422 standards using a single IC footprint. Consider the integrated termination feature if board space is limited and standard 120-ohm bus termination is required. Verify that the 3V to 5.5V supply range aligns with the target system voltage rails.

Drivers, Receivers, Transceivers Part Context

The LTC2870 belongs to Analog Devices' family of multiprotocol transceivers designed to streamline serial interface design. It consolidates multiple protocol capabilities into one device, reducing inventory complexity. The CFEPBF variant specifically denotes the commercial temperature range and SSOP packaging option within this product line.

Drivers, Receivers, Transceivers Replacement Considerations

Publicly confirmed substitute part numbers include LTC2870CUFD and LTC2870IFE. These alternatives share the same core functionality but may differ in package style or operating temperature range. Verify pin compatibility and electrical specifications before substitution.
