74AHCT1G14QSE-7

Overview

The 74AHCT1G14QSE-7 is a single Schmitt-trigger inverter from Diodes Incorporated, designed for automotive applications. It operates within a supply voltage range of 4.5V to 5.5V and features standard push-pull outputs with ±8mA drive capability at 5.0V. The device provides balanced propagation delays and input tolerance for slower rise/fall times. It is AEC-Q100 qualified for Grade 1 ambient temperature operation (-40°C to +125°C) and housed in an SOT-353 package.

Feature Summary

• Schmitt-trigger action at all inputs to ensure circuit tolerance for slower input rise and fall times
• AEC-Q100 qualified for Grade 1 ambient temperature operation ranging from -40°C to +125°C
• Standard push-pull output configuration providing balanced drive capability
• Inputs are not limited by VCC, allowing flexible interfacing

Applications

• Automotive applications requiring specific change control
• Industrial computing, controls, and automation systems
• High reliability networking and communications equipment
• Industrial and agricultural equipment

Procurement Notes

Verify the component matches the exact part number 74AHCT1G14QSE-7, ensuring the 'SE' suffix corresponds to the SOT-353 package. Confirm that the supplier provides documentation verifying AEC-Q100 qualification and IATF 16949 manufacturing certification. Check for RoHS compliance and lead-free status as specified in the datasheet notes. Ensure the ordering quantity aligns with the standard 3,000-unit tape and reel packaging format.

Selection Notes

Select this component when a single inverter with hysteresis is required for noisy environments or slow signal transitions. It is suitable for designs needing automotive-grade reliability under Grade 1 temperature conditions. The AHCT logic family ensures compatibility with CMOS inputs while operating at 5V. Consider the SOT-353 package size if space-constrained surface mount assembly is necessary.

Part Context

This device belongs to the 74AHCT series of logic devices manufactured by Diodes Incorporated. It is specifically engineered for automotive use, meeting strict quality standards including PPAP capability. The product line includes various logic functions packaged in small form factors like SOT-25 and SOT-353, catering to modern electronic design requirements for compactness and high performance.

Replacement Considerations

The 74AHCT1G14QW5-7 serves as a direct functional substitute using the SOT-25 package instead of SOT-353. Both parts share identical electrical characteristics and automotive qualifications. Verify pinout compatibility and physical footprint differences before swapping packages in existing PCB layouts.
