74AUP3G0434GSX

Overview

The Nexperia 74AUP3G0434GSX is a low-power logic device featuring one dual inverter and one single buffer. It operates within a supply voltage range of 0.8 V to 3.6 V and supports an ambient temperature range from -40 °C to +125 °C. The component utilizes Schmitt trigger inputs for noise immunity and includes IOFF circuitry for partial power-down applications. It is housed in an XSON8 package (SOT1203) with dimensions of 1.35 mm by 1.0 mm.

Feature Summary

• Schmitt trigger action on all inputs ensures tolerance for slow input rise and fall times across the entire operating voltage range.
• IOFF circuitry disables outputs during power-down, preventing damaging backflow currents when the device is unpowered.
• Low static power consumption with maximum ICC of 0.9 μA at extended temperatures.
• High ESD protection capabilities exceeding 5000 V via Human Body Model and 1000 V via Charged Device Model.

Applications

• Wave and pulse shaping circuits
• Partial power-down mode systems requiring backflow prevention
• Mixed-voltage signal translation environments

Procurement Notes

Verify the specific ordering suffix GS against the official Nexperia datasheet to confirm the SOT1203 XSON8 package variant. Ensure that the required temperature grade (-40 °C to +125 °C) matches the application constraints. Confirm RoHS compliance status through current manufacturer documentation prior to final procurement decisions.

Selection Notes

Select this component for designs requiring combined inversion and buffering functions in a minimal footprint. The wide supply voltage compatibility allows operation in low-power portable electronics. Verify that the load capacitance requirements align with the specified propagation delay characteristics for the target supply voltage.

Part Context

This part belongs to the 74AUP series of low-power CMOS logic devices manufactured by Nexperia. The AUP family is characterized by high speed and low power consumption, suitable for battery-operated applications. The 74AUP3G0434 specifically integrates three independent logic gates into a single compact package.

Replacement Considerations

Check for direct pin-compatible alternatives such as the 74AUP3G0434GT or 74AUP3G0434GN if different XSON8 package dimensions are required. Verify electrical specifications match before substituting.
