74HC14N-Q100U

Overview

The 74HC14N-Q100U is a hex inverting Schmitt trigger manufactured by Nexperia, operating within the HC logic family. It features six independent inverters with Schmitt-trigger inputs to transform slowly changing signals into sharply defined outputs. The device supports a supply voltage range of 2.0 V to 6.0 V and operates from -40 °C to +125 °C. It complies with AEC-Q100 Grade 1 standards for automotive applications, offering high noise immunity and low power dissipation.

Feature Summary

• Schmitt-trigger inputs provide jitter-free output signals from slowly changing input waveforms
• Qualified to AEC-Q100 Grade 1 standards for automotive reliability
• Wide supply voltage operation from 2.0 V to 6.0 V
• High noise immunity with CMOS low power dissipation characteristics

Applications

• Automotive signal conditioning circuits
• Pulse generation and shaping
• Oscillator circuits requiring hysteresis
• Transitioning noisy digital signals to clean logic levels

Procurement Notes

Verify the manufacturer designation carefully, as the model prefix indicates NXP USA Inc., while official documentation typically lists Nexperia B.V. as the producer. Confirm the specific suffix 'U' against the official datasheet to ensure package and tape/reel specifications match your assembly requirements. Cross-reference the AEC-Q100 qualification status directly with the component marking to guarantee automotive grade compliance.

Selection Notes

Select this component when designing systems requiring robust noise rejection on digital inputs. The Schmitt-trigger functionality is essential for applications involving slow-rise or slow-fall time signals. Ensure the operating temperature range meets the environmental conditions, specifically noting the extended upper limit of +125 °C suitable for under-hood automotive environments.

Part Context

This part belongs to the 74HC14-Q100 series of hex inverters designed for automotive electronics. It shares functional similarities with other 74HC14 variants but is distinguished by its specific automotive qualification and packaging options. The series is widely used in vehicle control units and sensor interfaces where signal integrity is critical.

Replacement Considerations

Direct substitutes include the 74HC14PW-Q100 and 74HC14D-Q100 from Nexperia, which offer identical electrical performance in different packages. Other manufacturers such as ON Semiconductor (MM74HC14) provide functionally equivalent parts, though pinout and package dimensions must be verified for compatibility.
