74AUP1T04GXH

Overview

The Nexperia 74AUP1T04GXH is a single-channel inverter with voltage-level translator housed in a 5-X2SON (SOT1226-3) package. It operates within a supply voltage range of 2.3 V to 3.6 V and supports an input voltage up to 3.6 V. The device features Schmitt trigger inputs for noise immunity and includes IOFF circuitry for partial power-down applications. Static supply current is limited to 1.2 µA at 25 °C and 3.5 µA at 125 °C. Propagation delay ranges from 0.5 ns to 11.9 ns depending on load capacitance and temperature.

Feature Summary

• Provides logic-level translation by accepting 1.8 V low-voltage CMOS signals while operating from 2.5 V or 3.3 V supplies.
• Schmitt trigger inputs ensure tolerance to slower input rise and fall times across the entire supply voltage range.
• IOFF circuitry disables the output during power-down to prevent damaging backflow currents.

Applications

• Logic-level translation between 1.8 V and 3.3 V domains
• Partial power-down mode operation in battery-powered systems
• Signal inversion in mixed-voltage environments

Procurement Notes

Verify the specific suffix 'GXH' against the manufacturer's latest ordering information to confirm the X2SON5 package type and tape-and-reel packaging configuration. Ensure that the procurement documentation aligns with the SOT1226-3 outline dimensions and marking codes specified in the product data sheet revision 4.

Selection Notes

Select this component when a single inverting function with voltage translation is required in space-constrained designs. The X2SON5 package offers a compact footprint suitable for high-density PCB layouts. Consider the propagation delay variations under different load capacitances and temperature conditions to ensure signal integrity meets system timing requirements.

Part Context

This part belongs to the 74AUP series, which is characterized by low power consumption and high-speed performance. The 74AUP1T04 provides a single inverter function, while the GXH suffix specifically denotes the X2SON5 package variant. This family is designed for applications requiring efficient power management alongside reliable signal processing in portable electronics.

Replacement Considerations

The 74AUP1T04GW serves as a pin-compatible alternative utilizing the TSSOP5 package. Designers must verify that the physical dimensions and thermal characteristics of the replacement package meet the mechanical constraints of the existing design.

FAQ

How does the IOFF circuitry function?

The IOFF circuitry disables the output when the device is powered down, preventing damaging backflow current through the device if its supply voltage drops below the level of the input/output pins.

What is the maximum input voltage supported?

The inputs are tolerant to voltages up to 3.6 V, allowing the device to interface with 1.8 V low-voltage CMOS signals even when operating from a higher supply voltage.
