HC1-5524-5

Telecom Overview

The HC1-5524-5 is a Subscriber Line Interface Concept (SLIC) integrated circuit manufactured by Harris Corporation. It is designed for telecom applications, supporting both 2-wire and 4-wire interfaces within a single circuit configuration. The device operates with a negative supply voltage range of -20V to -28V. It is housed in a 28-CERDIP package. This component facilitates the necessary interface functions for subscriber line connections in telecommunications systems.

Telecom Feature Summary

• Supports dual-mode operation for both 2-wire and 4-wire subscriber line interfaces
• Integrated circuit design specifically optimized for telecom subscriber line applications
• Operates on a dedicated negative voltage supply rail

Telecom Applications

• Telecommunications subscriber line interface circuits
• 2-wire telephone line connection systems
• 4-wire telephony interface implementations

Telecom Procurement Notes

Verify the specific manufacturer source, as Harris Corporation assets have been acquired by other entities such as L3Harris or Rochester Electronics. Confirm the package type matches the 28-CERDIP specification. Check RoHS compliance status, as older Harris components may not meet current environmental standards. Ensure the supply voltage requirements align with your system's -20V to -28V range before procurement.

Telecom Selection Notes

Select this component when a dedicated SLIC solution is required for legacy or standard telecom infrastructure. It is suitable for designs needing integrated 2-wire and 4-wire support in a single channel. Consider the ceramic DIP packaging for through-hole mounting requirements. Verify that the negative supply voltage availability in the target system matches the specified operating range.

Telecom Part Context

This part belongs to the Harris Corporation SLIC product family, which provides interface solutions for telecommunications networks. These components are critical for connecting end-user telephones to the central office switching equipment. The HC1-5524-5 represents a specific variant within this lineage, focusing on standard subscriber line functionalities.

Telecom Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Other Harris SLIC variants like the HC1-5509B-5 exist but differ significantly in supply voltage specifications (-42V to -58V). Cross-referencing with L3Harris or Rochester Electronics catalogs is recommended for potential equivalents.
