74AUP2G3404GF,125

Overview

The Nexperia 74AUP2G3404GF,125 is a low-power buffer and inverter featuring Schmitt trigger inputs for noise immunity. It integrates one non-inverting buffer and one inverter within a single XSON6 (SOT891) package. The device operates across a wide supply voltage range of 0.8 V to 3.6 V with CMOS low power dissipation. It includes IOFF circuitry for partial power-down applications, preventing backflow current when powered down.

Feature Summary

• Schmitt trigger action at all inputs ensures tolerance of slower input rise and fall times.
• IOFF circuitry disables outputs to prevent damaging backflow current during partial power-down.
• High noise immunity with overvoltage tolerant inputs up to the supply voltage limit.

Applications

• Partial power-down mode operation
• Signal buffering and inversion in low-voltage logic circuits
• Noise-immune signal transmission

Procurement Notes

Verify the specific ordering suffix GF, which denotes the XSON6 SOT891 package configuration. Confirm that the required temperature range aligns with the -40 °C to +125 °C specification provided in the datasheet. Ensure compatibility with the 0.8 V to 3.6 V operating voltage range for your target application design.

Selection Notes

Select this component for designs requiring both buffering and inversion functions in a minimal footprint. The inclusion of Schmitt triggers makes it suitable for noisy environments or signals with slow transition times. Verify that the system voltage remains within the 0.8 V to 3.6 V range to ensure proper functionality and adherence to static characteristics.

Part Context

This part belongs to the 74AUP2G3404 family of low-power CMOS logic devices. While other packages like TSSOP6 (GW), XSON6 (GM, GS), and XSON6 (GN) exist for the base type number, the GF suffix specifically identifies the XSON6 SOT891 variant. This family emphasizes low power consumption and high noise immunity across various supply voltages.

Replacement Considerations

Direct replacements must match the 74AUP2G3404 function and XSON6 SOT891 package. Other variants such as 74AUP2G3404GM, 74AUP2G3404GS, or 74AUP2G3404GN offer identical electrical performance but differ in physical package dimensions. Ensure pinout compatibility before substitution.
