Telecom Procurement Notes

Verify the manufacturer designation as Harris Corporation or Intersil Corporation, as product lines were acquired. Confirm the package type is 28-PLCC (11.51x11.51 mm). Ensure the specific suffix CM96 matches the required tape and reel configuration if applicable. Check for RoHS compliance status depending on the production batch date. Validate that the part is active or obsolescence status aligns with long-term supply requirements.

Telecom Selection Notes

Select this component for analog subscriber line interfaces requiring ITU compliance. It is suitable for CO and PABX switches needing integrated SLIC functions. Consider the low power standby feature for energy efficiency. Verify compatibility with existing 2-wire and 4-wire system architectures. Ensure thermal management features meet the application's environmental constraints.

Telecom Part Context

The HC5526CM96 belongs to the HC55xx series of Subscriber Line Interface Circuits from Harris Corporation. This series includes variants like the HC5520CQ and HC5521. These components are standard solutions for analog telephony infrastructure. The HC5526 specifically emphasizes low power standby operation compared to earlier models in the family.

Telecom Replacement Considerations

The HC5520CQ is a related SLIC variant but lacks the specific low power standby emphasis of the HC5526. Cross-reference with Intersil datasheets for equivalent pinouts and electrical characteristics. Verify functional compatibility before substituting with other SLIC devices.
