- Microprocessor-controlled measurement systems
Procurement Notes
Verify component authenticity through authorized Renesas Electronics distributors or legacy Intersil channels. Confirm package integrity and pinout alignment with the 16-CERDIP specification. Request manufacturer documentation to validate part lineage given the corporate acquisition history.
Selection Notes
Evaluate the 400 Ohm on-resistance against system accuracy requirements. Ensure the 16-pin CERDIP footprint matches the target PCB layout. Consider thermal dissipation limits relative to the 27.5 mW power rating during continuous operation.
Part Context
This component belongs to the HI-1818A family of low-resistance analog switches. Intersil was acquired by Renesas Electronics, integrating this technology into their broader portfolio of precision analog and mixed-signal solutions for industrial and medical markets.
Replacement Considerations
Consult official product legacy documents for confirmed substitute part numbers. Verify functional equivalence regarding channel count, package dimensions, and electrical characteristics before implementation.
