Analog Switches, Multiplexers, Demultiplexers 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.

Analog Switches, Multiplexers, Demultiplexers 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.

Analog Switches, Multiplexers, Demultiplexers 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.

Analog Switches, Multiplexers, Demultiplexers 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.
