74AHC1G14QSE-7

Overview

The Diodes Incorporated 74AHC1G14QSE-7 is an automotive-compliant single Schmitt-trigger inverter gate designed for operation with a power supply range of 2.0V to 5.5V. It features standard push-pull outputs and balanced propagation delays. The device operates within Grade 1 ambient temperature conditions from -40°C to +125°C. It provides ±8mA output drive at 4.5V and includes ESD protection exceeding 2000V Human Body Model and 1000V Charged Device Model per AEC-Q100 standards.

Feature Summary

• Schmitt trigger action at all inputs makes the circuit tolerant for slower input rise and fall times
• Inputs are not limited by VCC, providing flexible interface capabilities
• Balanced propagation delays and balanced drive capability ensure consistent signal performance
• ESD protection tested per AEC-Q100 exceeds 2000V Human Body Model and 1000V Charged Device Model

Applications

• Automotive applications within grade 1 temperature range
• Industrial computing/controls/automations
• High reliability networking/communications
• Industrial/agricultural equipment

Procurement Notes

Verify that the specific part number suffix matches the required package type, as the QSE variant corresponds to the SOT353 package. Confirm compliance requirements such as RoHS and lead-free status directly with the manufacturer documentation. Ensure the ordering quantity aligns with the standard tape and reel packing quantity specified in the official datasheet to avoid packaging discrepancies during procurement.

Selection Notes

Select this component when an inverting function with hysteresis is required for noisy environments or slow signal transitions. The wide operating voltage range supports various logic levels. Verify that the thermal resistance characteristics of the SOT353 package meet the system's heat dissipation needs. Ensure the application does not exceed the absolute maximum ratings for continuous output current or junction temperature under worst-case operating conditions.

Part Context

This component belongs to the 74AHC1G series of single-gate logic devices manufactured by Diodes Incorporated. The 'Q' designation indicates it is qualified for automotive applications according to AEC-Q100 standards. The 'SE' suffix specifically identifies the SOT353 surface-mount package. This family offers low-power CMOS technology suitable for portable and space-constrained electronic designs requiring robust noise immunity.

Replacement Considerations

Direct replacements must match the AHC logic family, Schmitt-trigger functionality, and SOT353 package. Verify that any substitute component meets the same AEC-Q100 qualification and IATF 16949 manufacturing standards if used in automotive contexts. Check pinout compatibility and electrical parameters such as propagation delay and output drive current.
