74HCT14BQ-Q100,115

Overview

The Nexperia 74HCT14BQ-Q100,115 is a hex inverting Schmitt trigger integrated circuit designed for automotive applications. It features HCT logic levels allowing TTL interfacing and includes input clamp diodes. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. It is housed in a DHVQFN14 package (SOT762-1) with side-wettable flanks.

Feature Summary

• Automotive qualification according to AEC-Q100 Grade 1 standards
• Schmitt-trigger inputs convert slowly changing signals into jitter-free outputs
• DHVQFN package with side-wettable flanks enables automatic optical inspection

Applications

• Wave and pulse shapers
• Astable multivibrators
• Monostable multivibrators

Procurement Notes

Verify the specific ordering suffix

Selection Notes

Select this component when TTL-compatible logic levels are required alongside Schmitt-trigger noise immunity. The DHVQFN package is suitable for space-constrained designs requiring thermal enhancement and reliable solder joint inspection capabilities.
