Telecom Procurement Notes

Verify availability status carefully as this part is marked discontinued at several major distributors including Digi-Key. Confirm exact package type PLCC-28/LCC-28 compatibility with existing PCB footprints. Ensure RoHS compliance requirements are met if applicable to your manufacturing standards. Check for valid replacement options from Infineon or third-party equivalents due to end-of-life status.

Telecom Selection Notes

Select this component only if legacy support for FlexiSLIC architecture is required. Consider the 5V operating voltage constraint against system power rails. Evaluate the PLCC-28 package constraints for modern assembly processes. Assess long-term supply chain risks given the discontinued status. Verify electrical specifications against current design requirements before final selection.
