74LVC14ABQ-Q100X

Inverter Gates Overview

The Nexperia 74LVC14ABQ-Q100X is a hex inverting Schmitt trigger with 5 V tolerant inputs, qualified to AEC-Q100 Grade 1. It operates on a supply voltage range of 1.2 V to 3.6 V and supports an input voltage up to 5.5 V. The device functions within an ambient temperature range of -40 °C to +125 °C. It is housed in a DHVQFN14 package (SOT762-1) measuring 2.5 × 3 × 0.85 mm. Propagation delay ranges from 1.0 ns to 14.7 ns depending on voltage.

Inverter Gates Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards for reliable operation in vehicle environments.
• Features 5 V tolerant inputs allowing direct interfacing between 3.3 V logic and 5 V devices without level shifting.
• Schmitt-trigger inputs provide noise immunity and transform slowly changing signals into sharply defined output transitions.
• DHVQFN package includes side-wettable flanks enabling automatic optical inspection of solder joints.

Inverter Gates Applications

• Wave and pulse shapers for highly noisy environments
• Astable multivibrators
• Monostable multivibrators

Inverter Gates Procurement Notes

Verify the specific suffix 'X' corresponds to the tape and reel packaging configuration required for automated assembly processes. Confirm that the DHVQFN14 package variant matches the footprint constraints of the target PCB design. Ensure the AEC-Q100 Grade 1 qualification meets the thermal and reliability requirements of the intended automotive application environment.

Inverter Gates Selection Notes

Select this component when designing mixed-voltage systems requiring translation between 3.3 V and 5 V logic domains. The Schmitt-trigger functionality is essential for applications involving slow-rise-time signals or high-noise environments. Verify that the operating temperature range of -40 °C to +125 °C aligns with the environmental conditions of the final product deployment.

Inverter Gates Part Context

This part belongs to the Nexperia 74LVC14A-Q100 family of hex inverters. The ABQ suffix specifically denotes the DHVQFN14 package type (SOT762-1). Other variants in the series include SO14 and TSSOP14 packages, offering flexibility for different board space and thermal management requirements while maintaining identical electrical characteristics.

Inverter Gates Replacement Considerations

Direct substitutes within the same family include 74LVC14AD-Q100J (SO14 package) and 74LVC14APW-Q100J (TSSOP14 package). These alternatives share identical electrical specifications but require different PCB footprints due to distinct package dimensions and pin configurations.

Inverter Gates FAQ

Can the 74LVC14ABQ-Q100X interface directly with 5 V logic?

Yes, the inputs are 5 V tolerant and can accept voltages up to 5.5 V, allowing direct connection to 5 V devices even when powered by lower supply voltages.

What is the purpose of the Schmitt-trigger inputs?

The Schmitt-trigger action provides hysteresis, which eliminates noise-induced glitches and converts slowly changing input signals into clean, sharply defined output pulses.
