• Ioff circuitry enables partial power-down mode and prevents damaging back-drive currents
• ESD protection exceeds JESD 22 standards including 2000-V human-body model ratings

Applications

• Portable audio devices such as MP3 players and recorders
• Solid state drives for client and enterprise storage
• Wireless peripherals including headsets, keyboards, and mice

Procurement Notes

Verify the specific ordering suffix DBVR corresponds to the SOT-23 package type and tape-and-reel quantity. Confirm that the RoHS compliance status and lead finish match your assembly requirements. Ensure the operating temperature range aligns with your system's thermal design specifications before finalizing procurement.

Selection Notes

Select this component when low power consumption and high-speed inversion are required in space-constrained designs. The AUC series offers superior performance compared to standard CMOS families at sub-1-V voltages. Verify input voltage levels against the recommended operating conditions to ensure proper logic threshold compatibility.
