74AUP3G3404GNX

Overview

The Nexperia 74AUP3G3404GNX is a low-power dual buffer and single inverter housed in an XSON8 package (SOT1116). It operates on a supply voltage range of 0.8 V to 3.6 V with Schmitt trigger inputs for noise immunity. The device features IOFF circuitry for partial power-down applications, preventing backflow current. Static supply current is limited to 0.9 μA maximum at -40 °C to +85 °C. Propagation delay ranges from 2.1 ns to 4.3 ns depending on load capacitance and voltage.

Feature Summary

• Schmitt trigger action provides tolerance for slower input rise and fall times across the entire operating voltage range.
• IOFF circuitry enables partial power-down mode by disabling outputs to prevent damaging backflow currents.
• High noise immunity with low overshoot and undershoot characteristics compliant with JEDEC standards.

Applications

• Partial power-down systems requiring controlled output disablement
• Signal buffering in low-voltage digital logic circuits
• Inverting applications within mixed-signal environments

Procurement Notes

Verify the specific ordering suffix GN corresponds to the SOT1116 XSON8 package variant. Confirm that the required temperature range and electrical specifications align with the project's operational constraints before finalizing procurement decisions.

Selection Notes

Select this component when a combination of buffering and inversion is required within a minimal footprint. The XSON8 package offers a compact solution for space-constrained designs. Ensure the application voltage falls within the 0.8 V to 3.6 V range to utilize the specified performance characteristics effectively.

Part Context
