Telecom Procurement Notes

This component is currently listed as obsolete by the manufacturer. Verify availability through authorized distributors or surplus suppliers. Confirm that the 28-SOIC package matches your PCB footprint requirements. Ensure compatibility with existing -42V to -58V supply rails before integration into legacy telecom designs.

Telecom Selection Notes

Select this part only if designing for ITU CO/Loop Carrier architectures requiring a single-channel SLIC. The fixed 28-SOIC package limits board layout options. Consider the obsolete status when planning long-term production runs. Verify thermal management capabilities for the specified 200 mW dissipation in enclosed environments.

Telecom Part Context

Harris Corporation produced this SLIC for telecommunications infrastructure. The product falls under the ITU CO/Loop Carrier category. It serves as a specialized interface chip for connecting subscriber lines to central office equipment. The component represents legacy telecom hardware technology.

Telecom Replacement Considerations

No public confirmed substitute part numbers are available for this obsolete component.
