LE9530DETCT

Telecom Overview

The LE9530DETCT is a discontinued single-channel Subscriber Line Interface Circuit (SLIC) manufactured by Microchip Technology. Designed for telecom interface applications, it operates with a parallel interface and requires a 3.3V supply voltage with a typical supply current of 40mA. The component is housed in a 48-lead TQFP package and is RoHS compliant. It was officially End-of-Life (EOL) as of March 7, 2016.

Telecom Feature Summary

• Provides subscriber line interface circuit functionality for telecommunications systems
• Supports parallel digital interface connectivity
• Operates on a single 3.3V power supply rail

Telecom Applications

• Telecommunications equipment requiring subscriber line interfacing
• POTS (Plain Old Telephone Service) line interface circuits
• Voice gateway hardware

Telecom Procurement Notes

This component is obsolete and no longer in production. Verification of availability should focus on surplus distributors or secondary markets rather than authorized channels. Confirm the specific package variant matches design requirements, as end-of-life status implies limited long-term sourcing options.

Telecom Selection Notes

Designers seeking active alternatives should consider the LE9541 series from Microchip Technology. Verify pin compatibility and electrical specifications against the original SLIC requirements to ensure seamless integration into existing telecom infrastructure without redesigning the board layout.

Telecom Part Context

The LE9530DETCT belongs to the Microchip LE95xx family of telecom interface ICs. This series focuses on providing robust subscriber line interface solutions for voice communication networks. The device integrates necessary analog front-end functions required for connecting telephone lines to digital processing systems.

Telecom Replacement Considerations

The LE9541DUQCT is listed as a similar replacement part by Microchip Technology. Engineers should evaluate this alternative for functional equivalence and package compatibility before proceeding with procurement.
