74AUP3G14GSX

Overview

The Nexperia 74AUP3G14GSX is a low-power triple Schmitt trigger inverter housed in an XSON8 package (SOT1203). It operates within a supply voltage range of 0.8 V to 3.6 V and supports ambient temperatures from -40 °C to +125 °C. The device features IOFF circuitry for partial power-down applications, preventing backflow current. Static supply current is limited to 0.9 μA maximum at extended temperature ranges. Propagation delay reaches a maximum of 7.4 ns at 3.6 V with a 30 pF load.

Feature Summary

• Provides three inverting buffers with Schmitt trigger action to transform slowly changing signals into sharply defined outputs
• Includes IOFF circuitry that disables outputs during power-down to prevent damaging backflow currents
• Features high noise immunity with low overshoot and undershoot characteristics relative to the supply voltage

Applications

• Wave and pulse shaping
• Astable multivibrator circuits
• Monostable multivibrator circuits

Procurement Notes

Verify the specific ordering suffix matches the required package variant, as the base type number covers multiple packages. Confirm the temperature grade aligns with system requirements, noting the specified range extends to +125 °C. Ensure design accounts for the IOFF functionality if partial power-down states are utilized in the application architecture.

Selection Notes

Select this component when space-constrained designs require triple inversion with hysteresis in ultra-thin leadless packages. The wide voltage range supports low-power portable systems operating below standard logic levels. Verify input signal compatibility with the specified threshold voltages across the entire operating temperature range to ensure reliable switching.

Part Context

This part belongs to the 74AUP series of advanced ultra-low power CMOS logic devices. The 'GS' suffix specifically denotes the XSON8 package (SOT1203) with dimensions of 1.35 mm by 1.0 mm. It shares functional equivalence with other 74AUP3G14 variants differing only in physical footprint, such as the GT (SOT833-1) or GN (SOT1116) packages.

Replacement Considerations

Public confirmed substitute part numbers: 74AUP3G14GT, 74AUP3G14GN, 74AUP3G14DC.
