Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix '5' against official Intersil documentation to confirm pinout and electrical tolerances. Ensure the procurement source provides traceability certificates suitable for military or aerospace qualification requirements. Confirm that the lead time aligns with long-lead item constraints typical for this component class.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a ruggedized, single-channel analog switch with high voltage tolerance is required. Compare the 1.5 kΩ on-resistance against circuit load requirements. Verify that the CDIP package dimensions fit the available board space and that the through-hole mounting method is compatible with the assembly process.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the HI-546 series of analog multiplexers produced by Intersil, now part of Renesas Electronics. The series is characterized by its use in high-reliability applications where traditional silicon switches may fail due to environmental stress or radiation exposure.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Publicly confirmed substitute part numbers are not available in verified sources. Cross-reference with other Intersil HI-series devices only if pin compatibility and electrical parameters match exactly.
