Procurement Notes
Verify the specific suffix and grade against official Texas Instruments documentation before procurement. Confirm that the component meets the required AEC-Q100 qualification level for your target application. Ensure compatibility with your system's voltage levels and thermal management requirements. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Check for any recent lifecycle updates or obsolescence notices directly from the manufacturer.
Selection Notes
Select this component when a single-channel analog switch is required for automotive-grade applications. Consider its low on-resistance and high switching current capabilities for signal integrity. Evaluate the SOT-23-5 package size against available board space constraints. Verify that the extended temperature range aligns with your operational environment. Compare performance metrics against alternative switches if higher channel counts are needed.
