74AUP1G32GX,125

Overview

The Nexperia 74AUP1G32GX,125 is a single 2-input OR gate in the AUP logic series. 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 utilizes IOFF circuitry to prevent backflow current during partial power-down states. It is housed in an X2SON-5 (SOT1226-3) package with dimensions of 0.8 x 0.8 x 0.32 mm. Propagation delay ranges from 1.0 ns to 3.5 ns at 3.0 V to 3.6 V with a 5 pF load.

Feature Summary

• Schmitt-trigger action on all inputs ensures tolerance to slow input rise and fall times across the entire operating voltage range.
• IOFF circuitry enables partial power-down mode operation by disabling outputs to prevent potentially damaging backflow currents.
• High noise immunity with low noise overshoot and undershoot specified at less than 10% of VCC.

Applications

• Partial power-down applications requiring protection against backflow current
• Signal routing in systems with slow input transition rates
• Low-power digital logic implementations

Selection Notes

Select this component when a single 2-input OR function is required in extremely thin packages. The AUP series offers lower power consumption compared to standard CMOS families while maintaining high-speed performance suitable for portable electronics. Ensure the design accommodates the 0.8 V minimum supply voltage if operating at the lower end of the range.

Part Context

This part belongs to the Nexperia 74AUP family of low-power CMOS logic devices. The 'GX' designation specifically identifies the X2SON-5 (SOT1226-3) thermal-enhanced package variant. This family is designed for battery-powered applications where minimizing static and dynamic power dissipation is critical.

Replacement Considerations

Check datasheets for other 74AUP1G32 variants such as 74AUP1G32GW or 74AUP1G32GM. Verify that alternative packages provide compatible pinouts and thermal characteristics before substitution.
