HC3-5502A-5

Telecom Overview

The HC3-5502A-5 is a Subscriber Line Interface Circuit (SLIC) manufactured by Harris Corporation, designed for EIA/ITU PABX applications. It operates within a voltage supply range of -42V to -58V and 10.8V to 13.2V. The device consumes 580 mW of power and functions at operating temperatures between 0°C and 75°C. It utilizes a 24-DIP package with a width of 0.600 inches (15.24mm) and supports through-hole mounting.

Telecom Feature Summary

• Designed as a Subscriber Line Interface Concept (SLIC) for telecommunications systems
• Compliant with EIA and ITU standards for PABX environments
• Supports dual voltage supply ranges for flexible integration

Telecom Applications

• PABX subscriber line interfacing
• Telecommunications circuit design
• EIA/ITU compliant system implementation

Telecom Procurement Notes

Verify the manufacturer origin, specifically confirming Harris Corporation or its successors such as Narda-MITEQ, as corporate structures have changed. Ensure the package type matches the required 24-DIP specification. Check for RoHS compliance status if environmental regulations apply to your deployment. Confirm the specific suffix '-5' denotes the correct variant for your voltage and temperature requirements.

Telecom Selection Notes

Select this component when designing for standard EIA/ITU PABX architectures requiring a dedicated SLIC solution. Consider the 24-DIP package size for PCB layout constraints. Evaluate the thermal performance given the 580 mW power dissipation in enclosed telecom enclosures. Ensure the input voltage supplies align with the specified -42V to -58V and 10.8V to 13.2V ranges for proper operation.
