HC9P5504B-5X96

Telecom Overview

The HC9P5504B-5X96 is a monolithic Subscriber Line Interface Circuit (SLIC) designed for EIA/ITU PABX applications. It integrates BORSHT functions, including DC battery feed with 40mA loop current capability and internal ring relay driver. The device supports 5V or 12V operation via dielectric isolation process. Key parameters include a longitudinal balance of 58dB and controlled supply of battery feed current for short loops up to 41mA. It operates within a temperature range of 0°C to +75°C in a 24-pin SOICW package.

Telecom Feature Summary

• Integrates BORSHT functions on a single IC chip, eliminating bulky hybrid transformers.
• Provides selective denial of power to subscriber loops during system overload emergencies.
• Features internal ring relay driver for interfacing with negative superimposed ringing systems.
• Capable of direct operation with wide range of station battery voltages using dielectric isolation.

Telecom Applications

• Solid State Line Interface Circuit for Analog and Digital PBX Systems
• Direct Inward Dial (DID) Trunks
• Voice Messaging Systems

Telecom Procurement Notes

Verify the specific suffix 'X96' against official Renesas documentation to confirm tape-and-reel packaging configuration. Ensure compatibility with RoHS3 standards and check moisture sensitivity level requirements for surface mount assembly processes prior to ordering.

Telecom Selection Notes

Select this component for designs requiring pin-for-pin replacement of the HC-5504. Consider the 24-SOIC package dimensions and operating temperature range when defining thermal management strategies. Verify that the 40mA loop feed meets the specific line length requirements of the target telephony application.

Telecom Part Context

This part belongs to the HC9P5504B series of SLICs manufactured by Renesas Electronics, formerly Intersil. It is an evolution of the HC-5504, offering enhanced integration and reliability for modern digital PBX systems while maintaining compatibility with worldwide performance requirements.

Telecom Replacement Considerations

Officially documented as a pin-for-pin replacement for the HC-5504. Verify electrical specifications match legacy system requirements before substitution.
