Telecom Procurement Notes

Verify current availability status as this component may be discontinued or subject to limited supply constraints. Confirm RoHS compliance details and moisture sensitivity levels prior to procurement. Ensure the specific suffix matches the required temperature grade and packaging format for your design implementation.

Telecom Selection Notes

Select this part when designing for 3.3V logic systems requiring integrated ringing and line feed capabilities. Consider the PLCC-28 package constraints for PCB layout. Verify that the operating temperature range meets the environmental requirements of the target deployment zone compared to commercial variants.

Telecom Part Context

This component is part of the ISL5585A series, which includes variants like ISL5585AIMZ and ISL5585CIMZ. These devices share the core functionality of 3.3V ringing SLICs but differ in temperature ratings and package options such as QFN32. The manufacturer transitioned from Intersil to Renesas Electronics during the product lifecycle.

Telecom Replacement Considerations

Check for direct substitutes within the ISL5585A family with compatible suffixes. Verify pin-to-pin compatibility if replacing with other PLCC-28 SLICs from different manufacturers.
