74AUP2G3404GN/S500

Overview

The Nexperia 74AUP2G3404GN/S500 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 package (SOT1115). The device operates across a wide supply voltage range of 0.8 V to 3.6 V, ensuring compatibility with various logic families. It includes IOFF circuitry to prevent backflow current during partial power-down states. The component supports ambient temperatures from -40 °C to +125 °C and complies with JEDEC standards for multiple voltage levels.

Feature Summary

• Integrates a single buffer and a single inverter with Schmitt trigger action on all inputs.
• Features IOFF circuitry that disables outputs to prevent damaging backflow currents when powered down.
• Provides high noise immunity and overvoltage tolerant inputs up to the supply voltage level.

Applications

• Partial power-down applications requiring isolation of powered-down sections.
• Signal buffering and inversion in low-voltage digital systems.
• Interfaces requiring tolerance for slower input rise and fall times.

Procurement Notes

Verify the specific suffix 'GN' corresponds to the SOT1115 XSON6 package variant before ordering. Confirm the 'S500' designation matches the required reel quantity or packaging format with the distributor. Ensure the design accounts for the specified temperature range and voltage limits defined in the product data sheet.

Selection Notes

Select this component when a combined buffer and inverter function is needed in a minimal footprint. The XSON6 package offers space savings compared to traditional leaded packages. Consider the Schmitt trigger inputs if the application involves noisy signals or slow transition rates. Verify that the 0.8 V to 3.6 V operating range aligns with the system's supply rails.

Part Context

This device belongs to the 74AUP series of ultra-low-power CMOS logic gates. It is manufactured by Nexperia USA Inc. and is designed for portable and battery-operated applications where power consumption is critical. The part replaces older logic families while offering improved performance at lower voltages.

Replacement Considerations

Direct replacements include other 74AUP2G3404 variants such as 74AUP2G3404GM (SOT886), 74AUP2G3404GS (SOT1202), and 74AUP2G3404GW (SOT363-2/TSSOP6). These share identical electrical characteristics but differ in physical package dimensions and pinout orientation.

FAQ

How does the IOFF circuitry function?

The IOFF circuitry automatically disables the outputs when the device is powered down (VCC = 0 V), preventing damaging backflow current through the device from live input or output lines.

What is the purpose of the Schmitt trigger inputs?

Schmitt trigger action provides hysteresis, making the circuit tolerant of slower input rise and fall times across the entire supply voltage range, thereby improving noise immunity.
