LE88506DVC

Telecom Overview

The LE88506DVC is a dual-channel VoicePort interface integrated circuit manufactured by Microchip Technology. It features the SLAC (Serial Line Access Controller) architecture designed for telecommunications applications. The device is housed in a 64-pin TQFP package with dimensions of 10x10 mm. It operates within a standard industrial temperature range from -40°C to +85°C. The component supports FXS line interface functions and includes protection circuits for telephony lines.

Telecom Feature Summary

• Integrates two independent VoicePort channels with SLAC architecture for efficient serial line access control
• Provides built-in FXS line interface capabilities with integrated protection mechanisms
• Designed for robust operation in industrial environments across extended temperature ranges

Telecom Applications

• Telecommunications interface systems requiring dual channel voice processing
• FXS line interface implementations in central office or remote terminal equipment
• Industrial communication devices utilizing serial line access controller protocols

Telecom Procurement Notes

Verify the manufacturer origin, noting that Microsemi has been acquired by Microchip Technology. Confirm the specific ordering suffix corresponds to the 64-TQFP package variant. Ensure compliance with RoHS standards as indicated in official documentation. Cross-reference the part number against current Microchip catalogs to confirm active status and availability of updated datasheets.

Telecom Selection Notes

Select this component when dual-channel voice interface functionality is required within a compact surface-mount package. The SLAC architecture offers efficient data handling for telephony applications. Consider the 64-TQFP form factor for PCB layout constraints. Verify thermal requirements align with the specified -40°C to +85°C operating range for the intended environment.

Telecom Part Context

This IC belongs to the VoicePort family of telecommunications interface controllers. It serves as a bridge between digital signal processors and analog telephone lines. The device simplifies system design by integrating line interface and protocol control functions into a single chip, reducing component count and board space in telecom infrastructure.

Telecom Replacement Considerations

Consult Microchip Technology official documentation for direct pin-to-pin compatible substitutes within the LE88xx series. Verify functional equivalence regarding channel count and package dimensions before substitution.
