74AUP1G14GVH

Overview

The 74AUP1G14GVH is a single Schmitt trigger inverter from the Nexperia AUP series, housed in an SC-74A (SOT753) package. It operates within a supply voltage range of 0.8 V to 3.6 V and supports an ambient temperature range of -40 °C to +125 °C. The device features low static power consumption with a maximum ICC of 0.9 μA at 25 °C. Propagation delay ranges from 1.5 ns to 4.7 ns depending on load capacitance and voltage. It includes IOFF circuitry for partial power-down applications and provides ESD protection exceeding 5000 V HBM.

Feature Summary

• Schmitt-trigger action ensures high noise immunity and tolerance for slow input rise and fall times.
• IOFF circuitry disables outputs during power-down to prevent damaging backflow current.
• CMOS construction delivers very low static and dynamic power dissipation across the full voltage range.
• Inputs are overvoltage tolerant up to 3.6 V, allowing operation with mixed voltage interfaces.

Applications

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

Procurement Notes

Verify that the ordering suffix GVH corresponds specifically to the SC-74A (SOT753) package variant as documented in the official Nexperia data sheet. Confirm the manufacturing origin aligns with NXP USA Inc. or authorized Nexperia production lines. Ensure the component meets the specified RoHS compliance standards required for your assembly process before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring signal conditioning with hysteresis to eliminate noise on slow-moving signals. The SC-74A package offers a compact surface-mount solution suitable for space-constrained designs. Consider the propagation delay specifications relative to your system clock speeds and ensure the operating voltage remains within the 0.8 V to 3.6 V window for optimal performance.

Part Context

This device belongs to the 74AUP family of advanced ultra-low-power CMOS logic gates. The AUP series is engineered for portable and battery-operated applications where minimizing energy consumption is critical. The specific inverter function allows for logical inversion while providing robust signal integrity through its Schmitt-trigger input stage, distinguishing it from standard logic inverters lacking hysteresis.

Replacement Considerations

Direct pin-compatible replacements include other variants within the 74AUP1G14 family such as 74AUP1G14GW or 74AUP1G14GM, provided the package type matches the PCB footprint requirements. Verify that any substitute maintains the same electrical characteristics and thermal performance specifications.
