HC1-5509B-5

Telecom Overview

The HC1-5509B-5 is a Subscriber Line Interface Circuit (SLIC) manufactured by Harris Corporation, now part of L3Harris Technologies. Designed for telecommunications applications, this integrated circuit facilitates the connection between central office equipment and subscriber lines. The component operates within a supply voltage range of -42V to -58V for line power and 4.75V to 5.25V for logic. It features a single circuit configuration with a maximum power consumption of 200 mW. The device supports an operating temperature range from 0°C to 75°C and is housed in a 28-CERDIP package.

Telecom Feature Summary

• Provides integrated subscriber line interface functionality for telecommunication systems
• Supports dual voltage operation for line powering and logic control
• Designed for reliable performance in standard commercial temperature ranges

Telecom Applications

• Central office telephone exchange interfaces
• Subscriber line interface circuits in telecom networks

Telecom Procurement Notes

Verify manufacturer authenticity as Harris Corporation assets were acquired by L3Harris Technologies. Confirm package type matches 28-CERDIP specifications. Check RoHS compliance status against current manufacturing standards. Ensure operating temperature ratings align with specific deployment environments. Validate part number suffixes for any functional variations.

Telecom Selection Notes

Select this component for applications requiring dedicated SLIC functionality in traditional telephony infrastructure. Consider the 28-pin ceramic DIP package for through-hole mounting requirements. Evaluate thermal management needs given the 200 mW power dissipation rating. Verify compatibility with existing -48V telecom power architectures. Assess space constraints relative to the CDIP-28 footprint dimensions.

Telecom Part Context

This component belongs to the Harris Semiconductor SLIC product family, which was integrated into L3Harris Technologies following corporate mergers. The HC1 series represents specialized analog interface solutions for telecommunications markets. These parts are designed to meet industry standards for subscriber line interfacing in public switched telephone networks.

Telecom Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-reference with L3Harris official catalogs for potential equivalents. Verify pinout compatibility before considering alternative SLIC devices from other manufacturers.
