Analog Switches - Special Purpose Procurement Notes

Verify current availability status as the component may be subject to lifecycle changes. Confirm package integrity and RoHS compliance documentation prior to integration. Ensure sourcing from authorized distributors to guarantee authenticity and traceability of the semiconductor material.

Analog Switches - Special Purpose Selection Notes

Select this component when a 4:1 USB multiplexing function is required in space-constrained designs. The small UMLP footprint suits portable applications. Verify that the operating voltage range aligns with the system's power supply rails and that the USB 2.0 speed requirements are met by the switch characteristics.

Analog Switches - Special Purpose Part Context

This part belongs to the FSUSB series of USB switches and multiplexers from onsemi. It serves as a signal routing solution for managing multiple USB sources or destinations. The UM suffix indicates the specific 16-pin ultra-miniature leadless package variant used for dense PCB layouts.

Analog Switches - Special Purpose Replacement Considerations

The FSUSB73UMX is a similar 3:1 multiplexer from the same manufacturer. Verify pin compatibility and channel count differences before substitution. Other generic USB switches may require circuit redesign due to differing electrical characteristics or package dimensions.
