Analog Switches - Special Purpose Procurement Notes

Verify the manufacturer marking and date code on the component body against official Fairchild or onsemi documentation. Ensure the SC-70-6 package matches the specified footprint. Confirm RoHS compliance status if required for your assembly process, as historical batches may vary.

Analog Switches - Special Purpose Selection Notes

Select this component when a small form factor is critical for USB 2.0 signal switching. It is suitable for designs operating below 3.6 V where low standby power is a priority. Compare pin compatibility with existing PCB layouts before integration.

Analog Switches - Special Purpose Part Context

Fairchild Semiconductor was acquired by onsemi. This part belongs to the legacy Fairchild portfolio now managed under the onsemi brand. Product nomenclature and ordering information may have been updated during the integration process. Verify current availability through onsemi channels.

Analog Switches - Special Purpose Replacement Considerations

Check for direct equivalents such as the FSUSB23 series. Ensure voltage ratings and package dimensions match. Verify that any substitute maintains the same pinout configuration to avoid PCB redesign.
