MXL1544CAI+

Drivers, Receivers, Transceivers Overview

The MXL1544CAI+ is a four-driver/four-receiver multiprotocol transceiver operating from a single +5V supply. It supports V.28 (RS-232), V.10/V.11 (RS-449, V.36, EIA-530, X.21, RS-423), and V.35 protocols. The device operates within a temperature range of 0°C to +70°C and is housed in a 28-pin SSOP package. Supply currents vary by protocol: VCC current ranges from 1mA to 120mA depending on load; IEE ranges from 1mA to 12mA; IDD ranges from 1mA to 300mA. No-cable mode reduces supply current to less than 10µA.

Drivers, Receivers, Transceivers Feature Summary

• Software-selectable DTE/DCE configuration for flexible interface implementation
• True fail-safe operation ensuring logic HIGH receiver output under open or shorted input conditions
• Low power consumption with 0.5µA shutdown current in no-cable mode
• Thermal shutdown circuitry protects drivers against excessive power dissipation

Drivers, Receivers, Transceivers Applications

• Data Networking
• CSU and DSU
• Data Routers
• Telecommunication Equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the component authenticity through official Analog Devices channels or authorized distributors. Confirm the specific ordering suffix matches the required package and temperature grade. Check for RoHS compliance documentation as indicated in product specifications. Ensure the source provides valid traceability records for quality assurance purposes.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a software-configurable control signal transceiver is required for serial interfaces. It pairs with the MXL1543 for clock/data signals and MXL1344A for termination. Consider the MAX3175 variant if receiver input glitch rejection is necessary for noisy environments. Verify that the application requires the specific voltage levels supported by the +5V single-supply architecture.

Drivers, Receivers, Transceivers Part Context

The MXL1544/MAX3175 form part of a chipset with the MXL1543 and MXL1344A. This combination creates a complete software-selectable DTE or DCE interface port. The series supports multiple legacy serial standards including RS-232, RS-449, and V.35. The devices are pin-compatible with the LTC1544, LTC1543, and LTC1344A chipsets.

Drivers, Receivers, Transceivers Replacement Considerations

MXL1544CAI+ is pin-compatible with LTC1544AI+. The MAX3175CAI+ serves as a functional equivalent but includes additional receiver input glitch rejection circuitry.
