LTC1544IG#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC1544IG#TRPBF is a software-selectable multiprotocol transceiver featuring four drivers and four receivers. It supports RS232, RS449, EIA530, EIA530-A, V.35, V.36, and X.21 protocols via mode select pins M0, M1, and M2. Operating from a single 5V supply with charge pump support, it accommodates V.10, V.11, and V.28 electrical standards. The component is housed in a 28-lead SSOP package and operates within an industrial temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Software-configurable protocol selection for multiple serial interface standards
• Integrated fail-safe receiver operation to prevent floating input errors
• Dedicated no-cable mode that reduces power consumption and disables outputs when disconnected

Drivers, Receivers, Transceivers Applications

• Data networking equipment requiring flexible port configurations
• Channel Service Unit/Service Delivery Unit (CSU/DSU) implementations
• Data routers utilizing DB-25 connectors

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape-and-reel packaging upon purchase. Confirm the IG variant matches the required -40°C to +85°C operating temperature range for your application environment. Ensure the manufacturer designation corresponds to Analog Devices Inc. before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing interfaces requiring hardware-level protocol switching without external termination resistors. Pair with the LTC1344A or LTC1543 to complete DTE/DCE ports. Verify that the 28-lead SSOP footprint fits the PCB layout constraints and that the 5V supply voltage aligns with system power rails.

Drivers, Receivers, Transceivers Part Context
