Procurement Notes
Verify the specific datasheet version and ordering suffix to ensure compatibility with design requirements. Confirm package dimensions and thermal characteristics against PCB layout constraints. Check for any recent lifecycle status changes or alternative recommendations from the manufacturer before finalizing procurement plans.
Selection Notes
Select this component when dual SP4T switching is required in a minimal footprint. Consider the 5.2 Ohm on-resistance and bandwidth limitations relative to the signal frequency. Ensure the operating temperature range aligns with the system environment and that the QFN package is suitable for the assembly process.
Part Context
This part belongs to the STG3 series of analog switches, designed for low-voltage applications. It complements other multiplexers and switches in the portfolio, offering a balance between performance and size for portable and industrial electronics.
Replacement Considerations
Consult official substitution lists for direct replacements. Verify pinout compatibility and electrical parameter equivalence if considering alternatives.
