74AUP3G3404GDH

Overview

The Nexperia 74AUP3G3404GDH is a low-power dual buffer and single inverter featuring Schmitt trigger inputs. It operates across a supply voltage range of 0.8 V to 3.6 V with a maximum static power consumption of 1.4 μA at -40 °C to +125 °C. The device includes IOFF circuitry for partial power-down applications, preventing backflow current. It provides high noise immunity and complies with JEDEC standards for various voltage levels. ESD protection exceeds 5000 V (HBM) and 1000 V (CDM). Propagation delay ranges from 1.0 ns to 7.2 ns depending on load capacitance and voltage. It is specified for ambient temperatures from -40 °C to +125 °C.

Feature Summary

• Schmitt trigger action at all inputs ensures tolerance of slower input rise and fall times.
• IOFF circuitry enables partial power-down mode by disabling outputs to prevent damaging backflow current.
• High noise immunity with low overshoot and undershoot below 10% of VCC.
• Compliance with multiple JEDEC standards covering voltage ranges from 0.8 V to 3.6 V.

Applications

• Partial power-down applications requiring backflow current prevention
• Systems needing high noise immunity with slow input signal transitions
• Low-power logic buffering and inversion in portable devices

Procurement Notes

Verify the specific ordering suffix GDH corresponds to the XSON8 package (SOT833-1) as defined in the official datasheet. Confirm that the component status matches current production requirements, noting that package availability may vary. Ensure compliance with RoHS and REACH regulations as stated in the product documentation before finalizing procurement specifications.

Selection Notes

Select this component when designing circuits requiring mixed buffer and inverter functions within a single package. The wide supply voltage range supports operation from 0.8 V to 3.6 V, suitable for various logic families. Consider the thermal derating characteristics for total power dissipation if operating near the upper temperature limits. Verify that the required propagation delays align with the system timing constraints under expected load conditions.

Part Context

This device belongs to the 74AUP series of low-power CMOS logic ICs manufactured by Nexperia. It integrates three independent logic gates: two non-inverting buffers and one inverter. The series is characterized by high speed and low power consumption, making it suitable for battery-powered applications. The GDH suffix specifically denotes the XSON8 plastic extremely thin small outline package variant.

Replacement Considerations

The datasheet lists 74AUP3G3404DC, 74AUP3G3404GT, 74AUP3G3404GN, and 74AUP3G3404GS as alternative type numbers within the same family. These variants differ primarily in package style (VSSOP8 or different XSON8 dimensions) rather than electrical function. Verify pinout compatibility and physical footprint requirements when substituting.
