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 temperatures. 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 input signals into sharply defined output signals.
• Includes IOFF circuitry that disables outputs during power-down to prevent damaging backflow currents.
• Features high noise immunity with low overshoot and undershoot specifications relative to the supply voltage.

Applications

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

Procurement Notes

Verify the specific ordering suffix 'GS' corresponds to the SOT1203 XSON8 package variant when sourcing. Confirm the required temperature grade matches the -40 °C to +125 °C specification. Ensure design compatibility with the 0.8 V to 3.6 V operating range and validate ESD protection requirements against HBM Class 3A standards.

Selection Notes

Select this component for designs requiring ultra-low static power consumption alongside robust noise immunity. The integrated Schmitt triggers are suitable for cleaning noisy digital signals. Verify that the XSON8 footprint aligns with PCB layout constraints and that the thermal dissipation characteristics meet the system's power budget under maximum load conditions.

Part Context

This device belongs to the Nexperia 74AUP series, which utilizes advanced CMOS technology for optimized speed-to-power ratios. The 74AUP3G14 family provides multiple package options including VSSOP and various XSON formats. It is designed for mixed 1.8 V and 3.3 V logic applications requiring minimal power usage.

Replacement Considerations

Direct replacements must match the 74AUP3G14 logical function and XSON8 pinout. Verify that alternative suppliers offer the same SOT1203 package outline and identical electrical characteristics for propagation delay and supply current limits.
