Telecom Procurement Notes

Verify the manufacturer origin, as Harris Corporation's electronic components are now part of L3Harris Technologies following a 2019 merger. Ensure the specific suffix 'LC-9' matches the required operating temperature and package specifications. Confirm availability through authorized distributors or official L3Harris channels to guarantee authenticity and compliance with defense and space technology standards.

Telecom Selection Notes

Select this component for applications requiring half-duplex voice-to-data conversion in harsh environments. The -40°C to +85°C operating range supports industrial and military use cases. Consider the 44-lead PLCC package for surface-mount assembly. Verify compatibility with existing serial NRZ interfaces and system power requirements before integration.

Telecom Part Context

This component belongs to the HC series of modems developed by Harris Corporation, now under L3Harris Technologies. These ICs are primarily used in defense and space communication systems. The HC4P5504ALC-9 specifically addresses voice signal digitization needs in tactical radio networks and secure communication equipment.

Telecom Replacement Considerations

Direct substitutes may include other HC-series models from L3Harris with similar pinouts and functionality. Verify electrical parameters and package dimensions before substitution. Consult official L3Harris documentation for approved replacement lists.
