Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the manufacturer designation as ON Semiconductor due to corporate acquisition history. Confirm the specific suffix 'UCX' corresponds to the required WLCSP package and tape-and-reel quantity. Ensure compliance with RoHS directives if applicable to your region. Cross-reference the datasheet revision date to confirm pinout and electrical characteristics match your design requirements before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a single SPDT switch is required for low-voltage signal paths. It is appropriate for applications demanding minimal insertion loss and fast transition times. Consider the WLCSP footprint constraints during PCB layout. Compare against similar switches if higher channel counts or different voltage tolerances are needed. Verify that the operating temperature range meets your environmental specifications.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the FSA96xx series of analog switches, which are optimized for consumer electronics. These devices are commonly used in mobile phones, PDAs, and portable audio equipment. The series emphasizes small form factors and low power consumption. Fairchild Semiconductor developed this line before its acquisition by ON Semiconductor, which continues to support and manufacture these parts under the new brand identity.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Check for direct substitutes such as the FSA9681 or FSA9684 if channel count differs. Verify equivalent packages like WLCSP-12 or similar small outlines. Ensure voltage ratings and on-resistance values are compatible. Consult ON Semiconductor documentation for updated cross-reference lists.
