LTC2844IG#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2844IG#TRPBF is a 3.3V software-selectable multiprotocol transceiver housed in a 28-lead SSOP package. It integrates four drivers and four receivers to support RS232, RS449, EIA530, EIA530-A, V.35, V.36, and X.21 protocols. Operating from a single 3.3V supply with the companion LTC2846, it features TTL-compatible logic inputs and CMOS outputs. The device includes internal termination networks for various standards and supports DTE/DCE configuration via the DCE/DTE pin.

Drivers, Receivers, Transceivers Feature Summary

• Software-selectable protocol support for multiple serial interface standards
• Integrated cable termination networks eliminating external switching components
• Fail-safe receiver operation ensuring high output state during floating conditions

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when sourcing. Confirm the IG designation corresponds to the industrial temperature range of -40°C to +85°C. Ensure compatibility with the required 28-lead SSOP footprint during procurement planning.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing a compact multiprotocol interface requiring software-controlled standard selection. Pair with the LTC2846 to generate necessary voltage levels and handle clock/data signals. Verify that the 3.3V logic levels match the system controller requirements.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2844/LTC2846 chipset family designed for complete DTE or DTE interface ports. It serves as the control signal transceiver while the LTC2846 manages clock and data lines. Together they provide a unified solution for legacy serial interface implementations.
