Overview
The HI4-0508A-8 is a single-ended multiplexer manufactured by Intersil, now part of Renesas Electronics. It features one function with eight channels and utilizes CMOS technology. The device is housed in a 20-CLCC package measuring 8.89x8.89 mm. Key electrical characteristics include an on-resistance of 1.8 kOhm and a charge injection of 4 pC. The component supports fault protection and has a drain capacitance of 25 pF, designed for signal switching applications requiring high integrity.
Feature Summary
- Single-ended multiplexer configuration with eight distinct channels
- CMOS technology implementation for signal processing
- Integrated fault protection mechanisms for circuit safety
Applications
- Signal routing in industrial control systems
- Data acquisition channel selection
- Communication equipment interface switching
Procurement Notes
Verify the manufacturer status carefully, as Intersil was acquired by Renesas Electronics. Confirm whether the specific lot requires compatibility with current Renesas supply chains or legacy Intersil documentation. Ensure the package type matches the 20-CLCC specification and validate that the CMOS process aligns with system requirements before finalizing procurement orders.
Selection Notes
Select this component when an eight-channel single-ended multiplexer is required within a constrained footprint. The 1.8 kOhm on-resistance and low charge injection make it suitable for precision analog signal routing. Consider the 20-CLCC package dimensions for PCB layout planning and ensure the fault protection feature meets the specific application's safety standards.
Part Context
This component belongs to the HI4 series of analog switches and multiplexers produced by Intersil. Following the acquisition by Renesas Electronics, these parts are integrated into the broader portfolio of high-performance analog ICs. The HI4-0508A-8 represents a specialized solution for multi-channel signal management in compact electronic designs.
Replacement Considerations
Consult Renesas Electronics product legacy documents for officially confirmed substitute part numbers. Verify pinout compatibility and functional equivalence before replacing the component in existing designs.
