Procurement Notes
Verify the specific datasheet version and package configuration when sourcing. Confirm RoHS compliance status as it may vary by manufacturing batch or region. Ensure the supplier provides original manufacturer documentation to validate authenticity. Check for any specific handling requirements related to the LOG CMOS technology node used in production.
Selection Notes
Select this component when signal fidelity is paramount over raw switching speed. The LOG CMOS technology offers a balance of performance and power efficiency suitable for consumer electronics. Consider the trade-off between the enhanced linearity benefits and potential cost differences compared to standard CMOS alternatives. Evaluate system requirements for charge injection sensitivity before finalizing the design choice.
Part Context
This part belongs to onsemi's interface product portfolio, specifically within the analog switch category. It complements other signal conditioning components by providing reliable switching capabilities for mixed-signal environments. The LOG CMOS series targets applications demanding precise analog control without introducing significant noise or distortion into the signal chain.
Replacement Considerations
Direct substitutes should be sought from the same LOG CMOS family to maintain pinout and electrical characteristic compatibility. Verify that alternative parts offer comparable linearity and charge injection specs. Cross-reference package dimensions if mechanical constraints are strict.
