Overview
The HI4P0546-5 is a high-speed analog multiplexer manufactured by Harris Corporation. It features a single channel with four selectable inputs, designed for precision signal routing in data acquisition systems. The device utilizes CMOS technology and operates within a standard dual-supply voltage range, typically ±15V, to accommodate wide dynamic signal ranges. It offers low on-resistance and fast switching times, ensuring minimal signal distortion during transitions. The component is housed in a 20-pin DIP package, providing a robust mechanical interface for through-hole mounting on printed circuit boards.
Feature Summary
- Four-channel input multiplexing capability for efficient signal selection
- Low on-resistance for accurate signal transmission
- Fast switching speed suitable for high-frequency applications
- TTL and CMOS logic compatible control interfaces
Applications
- Data acquisition systems requiring multi-channel signal scanning
- Industrial process control instrumentation
- Medical equipment signal processing circuits
- Test and measurement devices
Procurement Notes
Verify the specific manufacturer source, as Harris Semiconductor assets have been acquired by other entities. Confirm that the part number corresponds to the original Harris specification rather than a generic equivalent. Check for RoHS compliance status if required for modern manufacturing standards, as older Harris parts may not meet current environmental regulations. Ensure the package type matches the intended PCB footprint.
Selection Notes
Select this component when a single-pole four-throw configuration is required for analog signal routing. Consider the on-resistance and bandwidth specifications relative to the signal frequency and amplitude. Evaluate the control logic compatibility with the system microcontroller or FPGA. Compare performance metrics against newer integrated solutions if space or power consumption is a critical constraint.
Part Context
The HI4P0546-5 belongs to the HI4P series of analog multiplexers from Harris Corporation. This series was widely used in industrial and scientific applications before the company's semiconductor division was restructured. The part represents a legacy component often found in existing designs for test equipment and automation systems.
Replacement Considerations
Potential substitutes include the MAX308 or MAX318 from Maxim Integrated, which offer similar 4-channel multiplexing functionality. The CD4051 is a common CMOS alternative but may differ in speed and on-resistance characteristics. Verify pinout compatibility and electrical parameters before substituting.
