Procurement Notes
This component has reached end-of-life status as confirmed by manufacturer product change notices. Verification of availability should focus on obsolete stock or alternative sources rather than standard distribution channels. Engineers must validate the specific revision level against current design requirements before procurement.
Selection Notes
Designers should consider the discontinued status when selecting this part for new products. The recommended replacement is the NLAS5223MNR2G. Evaluation of the substitute requires checking pin compatibility and electrical parameter alignment to ensure seamless integration without circuit redesign.
Part Context
The NLAS4684 series belongs to onsemi's portfolio of low-voltage analog switches designed for portable applications. This specific variant utilizes a microbump package technology to minimize board space. The family is characterized by high speed and low power consumption, targeting consumer electronics markets where size constraints are critical.
Replacement Considerations
The MFR recommends NLAS5223MNR2G as the direct replacement. Verify functional equivalence regarding pinout and electrical characteristics before implementation.
