74AUP3G3404GTX

Overview

The Nexperia 74AUP3G3404GTX is a low-power dual buffer and single inverter from the AUP logic family. It operates within a supply voltage range of 0.8 V to 3.6 V and features Schmitt trigger inputs for noise tolerance. The device includes IOFF circuitry for partial power-down applications, preventing backflow current. It is housed in an XSON8 package (SOT833-1) with dimensions of 1 × 1.95 × 0.5 mm. Static supply current is typically 0.5 μA at 25 °C. Propagation delay ranges from 1.1 ns to 5.6 ns depending on load capacitance and voltage.

Feature Summary

• Dual buffer and single inverter configuration with Schmitt trigger inputs
• IOFF circuitry enables partial power-down mode operation
• High noise immunity with low overshoot and undershoot
• ESD protection exceeding 5000 V (HBM) and 1000 V (CDM)

Applications

• Partial power-down systems requiring backflow prevention
• Signal buffering in low-voltage digital circuits
• Noise-tolerant signal transmission paths

Procurement Notes

Verify the ordering suffix 'GTX' corresponds to the XSON8 (SOT833-1) package variant as specified in the official datasheet. Confirm that the specific revision level matches design requirements, noting that product specifications may change without notice. Ensure compatibility with the required operating temperature range of -40 °C to +125 °C for the intended application environment.

Selection Notes

Select this component when a combination of buffering and inversion is required in a minimal footprint. The wide supply voltage range supports various low-voltage logic families. The inclusion of Schmitt triggers makes it suitable for interfaces with slow rise and fall times. Verify that the output drive capability meets the load requirements of the destination circuitry.

Part Context

This part belongs to the 74AUP series of low-power CMOS logic devices. The 74AUP3G3404 integrates three independent logic functions: two non-inverting buffers and one inverter. It is designed for applications demanding high speed and low power consumption across a broad voltage spectrum. The XSON8 package provides a compact solution for space-constrained designs.

Replacement Considerations

The 74AUP3G3404GT is the generic type number for this function and package. Other package variants such as 74AUP3G3404DC (VSSOP8), 74AUP3G3404GN (XSON8 SOT1116), and 74AUP3G3404GS (XSON8 SOT1203) offer identical electrical characteristics but different physical footprints.

FAQ
