74HC14D-Q100,118

Overview

The Nexperia 74HC14D-Q100,118 is a hex inverting Schmitt trigger compliant with AEC-Q100 Grade 1 standards for automotive use. It operates within a supply voltage range of 2.0 V to 6.0 V and supports ambient temperatures from -40 °C to +125 °C. The device features reduced input threshold levels for TTL interfacing and includes clamp diodes on inputs. It provides high noise immunity and CMOS low power dissipation. The component utilizes an SO14 plastic small outline package (SOT108-1) with 14 leads.

Feature Summary

• Automotive qualification according to AEC-Q100 Grade 1 standard
• Schmitt-trigger inputs transform slowly changing signals into sharply defined outputs
• Wide supply voltage range supporting 2.0 V to 6.0 V operation
• High noise immunity and unlimited input rise and fall times

Applications

• Wave and pulse shapers
• Astable multivibrators
• Monostable multivibrators

Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature grade. Confirm that the AEC-Q100 Grade 1 qualification aligns with target automotive application requirements. Ensure compatibility with existing PCB footprint specifications for the SO14 package before finalizing procurement decisions.

Selection Notes

Select this component when designing circuits requiring signal conditioning with hysteresis in automotive environments. The wide operating temperature range and robust ESD protection make it suitable for harsh conditions. Consider the specific logic family requirements regarding input voltage thresholds and propagation delays relative to system timing constraints.

Part Context

This part belongs to the Nexperia 74HC14-Q100 series, which includes variants like the 74HCT14D-Q100. The 'D' suffix indicates the SO14 package, while 'Q100' denotes automotive qualification. The ',118' suffix typically refers to the reel or tape packaging configuration provided by the manufacturer.

Replacement Considerations

Check for pin-compatible alternatives such as the 74HCT14D-Q100 if TTL-level input compatibility is preferred over standard HC levels. Verify that any substitute maintains the same AEC-Q100 Grade 1 qualification and SO14 package dimensions.
