Overview
The HI4-0518-8 is an analog multiplexer manufactured by Harris Corporation. It features a single function with eight independent channels, designed for signal routing applications in electronic systems. The device utilizes CMOS technology and is housed in a 20-pin LDCC plastic package. It operates with a nominal supply voltage of 15 V and supports a maximum operating temperature of 70 °C. The component has a maximum on-state resistance of 1000 Ω and draws a maximum supply current of 18 mA. It is classified under analog mixed-signal integrated circuits.
Feature Summary
- Provides eight-channel analog signal switching capability within a single integrated circuit
- Utilizes CMOS process technology for low power consumption and high reliability
- Features a 20-pin plastic LDCC package suitable for surface-mount assembly
Applications
- Data acquisition systems requiring multi-channel signal selection
- Industrial control equipment for sensor input routing
- Test and measurement instruments for signal path configuration
Procurement Notes
Verify the manufacturer origin as Harris Corporation or its successors, noting that original Harris semiconductor assets were acquired by other entities. Confirm the package type is the 20-pin LDCC variant and check RoHS compliance status, as older Harris components may not meet current environmental standards. Ensure the supply voltage requirements align with system design specifications before procurement.
Selection Notes
Select this component when an eight-channel analog switch is required with CMOS compatibility. Verify that the 1000 Ω on-state resistance meets the application's signal integrity needs. Consider the 15 V supply requirement and ensure the 70 °C maximum operating temperature is sufficient for the intended environment. Compare against newer equivalents if higher performance or modern packaging is desired.
Part Context
This part belongs to the HI4 series of analog multiplexers produced by Harris Semiconductor. The series typically includes various channel counts and package options. Harris Corporation was a significant player in the semiconductor industry before its assets were divested, leading to complex ownership histories for these legacy parts. The HI4-0518-8 specifically represents an eight-channel configuration in a plastic leaded chip carrier package.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Users should consult official datasheets from current manufacturers holding Harris semiconductor intellectual property for direct replacements.
