Analog Switches, Multiplexers, Demultiplexers Procurement Notes

This component is officially designated as End-of-Life (EOL) by the manufacturer. Production has ceased, and the part is subject to obsolescence. Verification of authenticity is critical when sourcing from secondary markets, as availability is limited to existing stock or surplus channels. Buyers should confirm the specific manufacturing lot date and ensure compliance with humidity sensitivity handling requirements prior to assembly.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Designers must account for the discontinued status of this part number during new product development. The HI4P0549-5Z belongs to the HI-549 family; however, pinouts and specifications may vary between variants. Engineers should review the official datasheet for the complete electrical characteristics and mechanical dimensions. Alternative solutions within the same portfolio or modern equivalents should be evaluated to ensure long-term supply chain stability and compatibility with current design constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

The HI4P0549-5Z is part of the HI-549 series of high-performance analog multiplexers originally developed by Intersil and now managed by Renesas Electronics. This series is characterized by its robust construction and suitability for demanding industrial applications. The specific model utilizes a PLCC package, distinguishing it from SOIC-based variants in the lineup. It represents a legacy component designed for precision signal switching tasks before subsequent generations of integrated switches were introduced.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the End-of-Life status, direct replacements require manual verification against the official datasheet specifications. Designers should consult the manufacturer's discontinuance notices or technical support for recommended cross-reference parts that match the 28-pin PLCC form factor and 2 x 4:1 configuration.
