Overview
The HI3-0546-5 is a high-speed analog multiplexer switch manufactured by Intersil. It features a single channel configuration with built-in protection, housed in a hermetic ceramic dual in-line package (CDIP). The device operates as a solid-state relay for signal routing applications. Key electrical specifications include a maximum on-resistance of 1.5 kΩ and a maximum operating temperature of 125 °C. It supports a maximum supply voltage of 22 V and a dual supply voltage of 18 V. The component utilizes enhancement mode FET technology and is designed for military-grade reliability standards.
Feature Summary
- Hermetically sealed ceramic construction for harsh environment durability
- Integrated overvoltage protection capabilities
- Single-channel analog signal switching functionality
Applications
- Military communication systems requiring radiation tolerance
- Test and measurement equipment signal routing
- Aerospace data acquisition systems
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.
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.
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.
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.
