MT9074AL1

Telecom Overview

The MT9074AL1 is a single-channel telecommunications transceiver manufactured by Microchip Technology. It operates within a supply voltage range of 4.75V to 5.25V and draws a maximum supply current of 200mA. The device is designed for surface-mount installation in a 100-MQFP package, specifically identified as 100-BQFP with dimensions of 14x20 mm. It supports an extended operating temperature range from -40°C to +85°C, ensuring reliability in industrial environments. This component functions as a dedicated interface IC for telecom applications.

Telecom Feature Summary

• Integrated single-channel transceiver functionality for telecommunications interfaces
• Industrial-grade thermal stability supporting wide ambient temperature variations
• Surface-mount compatible design utilizing a high-pin-count quad flat package

Telecom Applications

• Telecommunications equipment requiring dedicated interface transceivers
• Industrial control systems operating in extreme temperature conditions
• Embedded communication modules needing robust signal transmission

Telecom Procurement Notes

Verify the specific package marking and date code against official Microchip documentation to ensure authenticity. Confirm that the 100-MQFP footprint matches the target PCB layout precisely. Check for any recent Product Change Notices regarding marking or packaging updates. Ensure the supplier provides traceability documentation consistent with Microchip standards. Validate the component status as active or obsolete before finalizing procurement plans.

Telecom Selection Notes

Select this component when a single-channel telecom transceiver is required for harsh environments. The 100-MQFP package suits designs needing dense interconnects on a limited board area. Verify that the 5V logic compatibility aligns with the system's power domain. Consider the 200mA current draw for adequate power plane design and thermal management strategies.

Telecom Part Context

The MT9074AL1 belongs to the MT9074 family of telecommunications interface devices produced by Microchip Technology. This series focuses on providing reliable signal conversion for telecom infrastructure. The AL1 suffix typically denotes specific package and temperature grade variations within the broader product line, distinguishing it from other pinout or environmental variants.

Telecom Replacement Considerations

Consult Microchip's official obsolescence notices for direct replacements. Cross-reference pinouts and electrical characteristics carefully if considering third-party alternatives. Verify that any substitute maintains the 100-MQFP form factor and industrial temperature rating.
