LTC1544IG#PBF

Drivers, Receivers, Transceivers Overview

The LTC1544IG#PBF is a 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 5V supply with an external charge pump, it provides complete DTE or DCE serial interface functionality. The device features mode selection via M0, M1, and M2 pins, enabling dynamic protocol switching without hardware changes.

• Data routers

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #PBF indicates lead-free compliance and RoHS adherence before procurement. Confirm the IG variant meets the required industrial temperature range of -40°C to +85°C. Ensure the 28-lead SSOP package dimensions align with the target PCB footprint. Validate that the intended application requires the specific driver/receiver count provided by this component.

Drivers, Receivers, Transceivers Selection Notes

Select the LTC1544IG#PBF when designing interfaces requiring flexible protocol support across RS232, V.35, and X.21 standards. This component is suitable for systems needing software-controlled DTE/DCE configuration. Pair with the LTC1543 for clock/data signals and the LTC1344A for cable termination if full multiprotocol capability is required. Ensure adequate decoupling capacitors are placed near the power pins.

Drivers, Receivers, Transceivers Part Context

The LTC1544 serves as the control signal transceiver within the Analog Devices multiprotocol interface family. It complements the LTC1543, which handles clock and data lines, to form a complete serial port solution. Together with the LTC1344A termination controller, these components enable a fully software-configurable DTE or DCE interface port.
