74AHC1G07QW5-7

Overview

The 74AHC1G07QW5-7 is an automotive-compliant single buffer gate with an open-drain output, manufactured by Diodes Incorporated. It operates within a supply voltage range of 2.0V to 5.5V and supports Grade 1 ambient temperature operation from -40°C to +125°C. The device features Schmitt trigger inputs for tolerance to slower rise and fall times, balanced propagation delays, and ESD protection exceeding 2000-V Human Body Model and 1000-V Charged Device Model standards per AEC-Q100.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 standards
• Open-drain output configuration enabling wired-OR or wired-AND logic functions
• Schmitt trigger action at all inputs to accommodate slow signal transitions
• CMOS low-power consumption design with balanced drive capability

Applications

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

Procurement Notes

Verify the component matches the exact part number 74AHC1G07QW5-7, ensuring the W5 suffix corresponds to the SOT25 package. Confirm that the Q suffix indicates AEC-Q100 automotive qualification. Check datasheet revision DS41449 Rev. 1-2 for current specifications. Ensure compliance with RoHS3 and REACH directives as stated in the manufacturer documentation.

Selection Notes

Select this component when an open-drain buffer is required for level shifting or driving loads connected to a separate pull-up voltage. The wide input voltage range allows compatibility with various logic families without being limited by VCC. Consider the SOT25 package size constraints and thermal resistance characteristics for PCB layout planning in high-temperature environments.

Part Context

This device belongs to the 74AHC1GxxQ series of single-function logic gates designed for automotive use. It shares the same logical function as other variants but differs in packaging options such as SOT353. The series emphasizes robustness through Schmitt triggers and high ESD ratings, making it suitable for harsh electromagnetic environments found in industrial and automotive sectors.

Replacement Considerations

The 74AHC1G07QSE-7 serves as a direct functional substitute utilizing the SOT353 package instead of SOT25. Both parts share identical electrical characteristics and automotive qualifications. Verify pinout compatibility and physical footprint differences before substitution in existing designs.
