Telecom Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct package type and temperature rating. Confirm RoHS compliance status through the latest datasheet or product change notification. Cross-reference the Mouser part number 494-LE9642PQC with the manufacturer's catalog to validate availability and lead times before finalizing procurement plans.

Telecom Selection Notes

Select this component when a single-channel SLIC with 150V tracking is required for telecom applications. Ensure the design accommodates the 48-QFN package dimensions and thermal requirements given the 1.5W power dissipation limit. Verify that the system power supply provides a stable 3.3V rail within the specified 3.135V to 3.465V operational window for reliable performance.

Telecom Part Context

The LE9642PQC belongs to Microchip's miSLIC family of Subscriber Line Interface Circuits. This series is engineered to provide essential analog front-end functions for telephone lines, including ringing generation, battery feed, and hybrid circuitry. The PQC suffix typically denotes a specific tape-and-reel or tray packaging option for the QFN-48 package, distinguishing it from other variants in the same functional family.

Telecom Replacement Considerations

Check the official Microchip cross-reference list for direct replacements. Consider the LE9651PQC for similar single-channel SLIC functionality if pin compatibility and feature sets align with the design requirements.
