LE9500CBJCT

Telecom Overview

The LE9500CBJCT is a single-channel Subscriber Line Interface Circuit (SLIC) manufactured by Microchip Technology. Designed for telecom interface applications, it operates with a 3.3V supply voltage and draws 40mA of supply current. The device utilizes a parallel interface and is housed in a 28-PLCC surface-mount package. It complies with RoHS3 standards and carries an EAR99 classification. The component has reached its End-of-Life date as of March 7, 2016.

Telecom Feature Summary

• Integrated subscriber line interface circuit functionality for telecommunications systems
• Surface-mount installation type compatible with automated assembly processes
• RoHS3 compliant construction supporting environmental regulatory requirements

Telecom Applications

• Telecommunications equipment requiring user line interface capabilities
• Digital subscriber line access multiplexers (DSLAMs)
• Central office switching systems

Telecom Procurement Notes

This component is officially discontinued and no longer manufactured by Microchip Technology. Verification of authenticity is critical when sourcing from secondary markets due to the end-of-life status. Buyers must confirm the specific manufacturing lot and revision level against original design specifications. Availability is limited to existing stock or surplus channels, requiring careful evaluation of storage history and moisture sensitivity levels prior to integration into new production cycles.

Telecom Selection Notes

Design engineers should evaluate alternative components due to the discontinuation of this part number. The LE9541CUQCT is identified as a similar replacement option within the manufacturer's portfolio. Compatibility assessments must include pinout verification, electrical parameter matching, and software configuration differences. Transitioning to newer generations may require schematic updates and board layout modifications to accommodate potential changes in package dimensions or thermal characteristics.

Telecom Part Context

The LE9500 series represents Microchip's legacy solutions for analog telephony interface requirements. This specific variant targets traditional voice and data transmission over copper lines. As technology evolved toward digital interfaces and higher bandwidth applications, newer integrated circuits replaced older SLIC designs. The 28-PLCC package reflects packaging standards prevalent during the product's active manufacturing period.

Telecom Replacement Considerations

The LE9541CUQCT is listed as a similar replacement by the distributor. Engineers must verify functional equivalence regarding voltage levels, interface protocols, and mechanical fit before substitution.
