Overview
The HI3-0546-9 is a single-ended multiplexer manufactured by Harris Corporation, belonging to the HI-546 series. It features 16 channels and is housed in a CDIP28 package. The device operates with dual power supplies of ±15 V and supports a maximum supply voltage of 22 V. Key electrical parameters include a maximum on-resistance of 1.5 kΩ, a maximum operating frequency of 2 MHz, and a maximum propagation delay of 500 ns. It provides overvoltage protection and is designed for applications requiring high channel density in analog signal routing.
Feature Summary
- Integrates 16 single-ended channels within a compact 28-pin ceramic dual in-line package.
- Includes built-in overvoltage protection to safeguard internal circuitry during abnormal input conditions.
- Supports dual power supply operation for versatile analog signal switching applications.
Applications
- Analog data acquisition systems requiring multi-channel signal selection.
- Test and measurement equipment utilizing high-density signal routing.
- Industrial control systems managing multiple sensor inputs.
Procurement Notes
Verify component authenticity through authorized distributors or certified secondary market suppliers due to potential obsolescence. Confirm package integrity and pin compatibility before integration. Request detailed lot traceability and storage history to ensure performance reliability. Validate specifications against current design requirements as this component may be subject to limited availability.
Selection Notes
Select the HI3-0546-9 when a 16-channel single-ended multiplexer with overvoltage protection is required. Ensure the application supports dual ±15 V power supplies and accommodates the specified 1.5 kΩ on-resistance. Consider the CDIP28 package constraints for PCB layout and thermal management compared to alternative plastic packages.
Part Context
This component is part of the HI-546 series of analog multiplexers produced by Harris Corporation, which was later acquired by Intersil and subsequently Renesas Electronics. The series is characterized by CMOS technology and high channel counts, serving legacy industrial and military applications where ceramic packaging and specific analog performance metrics are mandated.
Replacement Considerations
Potential substitutes include the HI1-0546-2 and HI3-0546-5 from the same family. Verify pinout compatibility and electrical parameter alignment, particularly regarding on-resistance and supply voltage ranges, before implementing any cross-replacement.
