74AHC1G14QW5-7

Overview

The Diodes Incorporated 74AHC1G14QW5-7 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 provides ±8mA output drive at 4.5V and utilizes CMOS technology for low-power consumption. Inputs are tolerant for slower rise and fall times, and the circuit includes ESD protection exceeding 2000-V Human Body Model and 1000-V Charged Device Model standards per AEC-Q100.

Feature Summary

• Automotive Grade 1 qualification with ambient temperature operation from -40°C to +125°C
• Schmitt trigger action at all inputs to ensure tolerance for slower input rise and fall times
• ESD protection tested per AEC-Q100, exceeding 2000-V Human Body Model and 1000-V Charged Device Model thresholds
• Totally lead-free, fully RoHS compliant, and halogen and antimony free

Applications

• Automotive applications within Grade 1 temperature range
• Industrial computing, controls, and automations
• High reliability networking and communications
• Industrial and agricultural equipment

Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the QW5 variant corresponds to the SOT25 package while other suffixes may indicate different physical footprints. Confirm compliance requirements such as PPAP capability and IATF 16949 manufacturing certification if the application demands strict automotive change control protocols. Ensure the design accounts for the specified operating voltage and temperature ranges during component selection.

Selection Notes

Select this component when an inverting function with hysteresis is required for noise immunity in slow-signal environments. The AHC family offers high-speed performance suitable for general-purpose logic applications. Consider the SOT25 package dimensions and thermal resistance characteristics if board space or heat dissipation is a constraint. Verify that the input voltage levels remain within the specified limits relative to the supply voltage.

Part Context

This part belongs to the 74AHC1G14Q series of single Schmitt-trigger inverters manufactured by Diodes Incorporated. The 'Q' designation indicates AEC-Q100 qualification for automotive use, while the 'W5' suffix specifies the SOT25 surface-mount package. It is part of the broader 74AHC logic family, which operates between 2.0V and 5.5V and is designed for low-power CMOS applications requiring robust signal integrity.

Replacement Considerations

The datasheet does not list specific public substitute part numbers. Cross-referencing requires matching the AHC logic family, Schmitt-trigger functionality, single inverter configuration, and SOT25 package constraints.
