HC4P5509B-9

Telecom Overview

The HC4P5509B-9 is a Subscriber Line Interface Circuit (SLIC) designed for ITU CO/Loop Carrier applications. It operates within a -42V to -58V supply range, typically utilizing -48V standard telecom voltage. The component is housed in a 44-LCC (J-Lead) package, also identified as 44-PLCC with dimensions of 16.58x16.58 mm. This integrated circuit manages loop current and provides essential interface functions for telecommunications subscriber lines.

Telecom Feature Summary

• Manages loop current by regulating feed voltage from the power supply
• Designed specifically for ITU Central Office and Loop Carrier environments
• Supports standard -48V telecom operating conditions

Telecom Applications

• ITU Central Office subscriber line interfacing
• Loop Carrier system implementations
• Telecommunications infrastructure hardware

Telecom Procurement Notes

Verify the specific manufacturer source, as Harris Corporation assets are often managed by Rochester Electronics LLC. Confirm RoHS compliance status, as some listings indicate non-compliance while others suggest lead-free variants. Ensure the package type matches the required 44-LCC or PLCC footprint for your design. Check for any ordering suffix variations that may affect electrical characteristics or packaging.

Telecom Selection Notes

Select this component when an ITU-compliant SLIC is required for central office or loop carrier architectures. The fixed -42V to -58V input range suits standard telecom power systems. Consider the 44-pin LCC package constraints during PCB layout. Verify availability through authorized distributors handling Harris Semiconductor legacy parts, as stock levels vary significantly between suppliers.

Telecom Part Context

This part belongs to the Harris Corporation telecommunications IC portfolio, specifically within the SLIC category. It is related to other components like the HC4P5524-9 and various HC series logic devices. The product represents legacy CMOS analog interface technology intended for robust telecom network equipment rather than consumer electronics.

Telecom Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Users must verify pinout compatibility and electrical specifications against potential alternatives from other manufacturers offering ITU-compliant SLICs in similar packages.
