HC55150CM

Telecom Overview

The HC55150CM is a telecommunications interface integrated circuit manufactured by Harris Corporation, functioning as a Line Interface Circuit (LIC) or Subscriber Line Interface Circuit (SLIC). It is designed for use in analog telephone systems to provide essential line interface functions. The component integrates protection features and signal processing capabilities required for connecting subscriber lines to the central office switching equipment.

Telecom Feature Summary

• Provides line interface functionality for analog telephony applications
• Integrates protection mechanisms for subscriber line circuits
• Supports standard signaling requirements for telephone networks

Telecom Applications

• Analog telephone line interface modules
• Central office switching equipment
• Subscriber line interface circuits (SLIC)

Telecom Procurement Notes

Verify the exact manufacturer origin, as Harris Corporation's semiconductor assets were acquired by Intersil and subsequently Renesas. Confirm that the HC55150CM designation corresponds to the specific package and temperature grade intended for your design. Check for obsolescence notices or alternate manufacturing site notifications associated with this part number before finalizing procurement plans.

Telecom Selection Notes

Select this component when designing legacy analog telephony interfaces requiring integrated line protection and signaling. Ensure compatibility with the system's voltage levels and signaling standards. Consider the availability status, as older telecom ICs may have limited supply chains or require verification of current production status through authorized distributors.

Telecom Part Context

Harris Corporation was a prominent manufacturer of electronic components before its semiconductor division was sold to Intersil. The HC55150 series represents a family of telecommunications interface chips used extensively in public switched telephone networks (PSTN). This specific model is part of the historical portfolio now managed under subsequent corporate ownership structures.
