Analog Switches - Special Purpose Procurement Notes

Verify the exact ordering suffix and tape/reel specifications against the current onsemi datasheet before procurement. Confirm that the requested part number matches the specific package variant required for your PCB layout. Ensure compliance with RoHS directives if applicable to your manufacturing region. Check for any recent lifecycle status updates or obsolescence notices directly from the manufacturer.

Analog Switches - Special Purpose Selection Notes

Select this component when a single-port USB 2.0 switch is required in a minimal footprint. The MicroPak package is ideal for space-constrained designs compared to larger QFN or TSSOP options. Consider the 3V to 3.6V supply range compatibility with your system's power rails. Evaluate the bidirectional nature of the switch against unidirectional alternatives if signal directionality is fixed.

Analog Switches - Special Purpose Part Context

The FSUSB20 series belongs to onsemi’s portfolio of low-voltage, ultra-low power USB switches. Originally developed by Fairchild Semiconductor, these components are widely used in consumer electronics for port expansion and protection. The L10X suffix typically denotes the specific 10-lead MicroPak packaging configuration within the broader FSUSB20 family.

Analog Switches - Special Purpose Replacement Considerations

FSUSB20BQX: Similar low-power USB switch but in a different package format. NLAS7222B: Dual DPDT switch offering two ports instead of one. FSUSB42UMX: Higher performance alternative with improved electrical characteristics.
