74AUP1G14GVH

Overview

The 74AUP1G14GVH is a single inverter with Schmitt-trigger input from the Nexperia AUP logic family, housed in an SC-74A (SOT753) package. It operates across a wide supply voltage range of 0.8 V to 3.6 V and supports ambient temperatures from -40 °C to +125 °C. The device features low static power consumption with a maximum ICC of 0.9 μA at 25 °C. It includes IOFF circuitry for partial power-down applications, preventing damaging backflow currents. ESD protection exceeds 5000 V (HBM) and 1000 V (CDM).

Feature Summary

• Schmitt-trigger inputs provide high noise immunity and tolerance for slow input rise and fall times.
• IOFF circuitry enables partial power-down mode by disabling outputs to prevent backflow current.
• Overvoltage tolerant inputs allow direct interfacing with higher voltage logic levels up to 3.6 V.

Applications

• Wave and pulse shapers
• Astable multivibrators
• Monostable multivibrators

Procurement Notes

Verify the specific ordering suffix 'H' against official Nexperia documentation to confirm reel packaging specifications, as standard datasheets may list generic package types without explicit tape-and-reel details. Ensure the component matches the SOT753 physical dimensions and pinout configuration required for the target PCB footprint. Cross-reference the manufacturing date code and lot traceability requirements with the supplier's certificate of conformity prior to final procurement authorization.

Selection Notes

Select this component when designing circuits requiring robust signal conditioning with Schmitt-trigger hysteresis in low-power environments. The AUP series is suitable for battery-operated devices due to its wide voltage range and minimal static current draw. Verify that the SC-74A package size fits within the available board space constraints. Confirm that the operating temperature range meets the environmental conditions of the end application.

Part Context

This part belongs to the 74AUP1G14 series of low-power Schmitt trigger inverters manufactured by Nexperia. The GVH designation specifically identifies the SC-74A surface-mount package variant. It is part of the broader 74AUP logic family, which offers performance improvements over previous generations while maintaining compatibility with standard digital logic interfaces.

Replacement Considerations

Direct replacements include other 74AUP1G14 variants such as 74AUP1G14GW or 74AUP1G14GM, provided the package type difference is accommodated in the design. Ensure any substitute maintains the same Schmitt-trigger characteristics and IOFF functionality.

FAQ

Does the 74AUP1G14GVH support partial power-down applications?

Yes, the device includes IOFF circuitry that disables the output to prevent potentially damaging backflow current when the device is powered down.

What is the input voltage tolerance of this inverter?

The inputs are overvoltage tolerant up to 3.6 V, allowing them to interface with systems operating at higher voltage levels than the supply voltage.
