74AHCT1G125QW5-7

Overview

The 74AHCT1G125QW5-7 is an automotive-compliant single non-inverting buffer with a 3-state output, manufactured by Diodes Incorporated. It operates within a supply voltage range of 4.5V to 5.5V and provides ±8mA output drive at 4.5V. The device features Schmitt trigger inputs for tolerance to slow rise/fall times and balanced propagation delays. It supports ambient temperature operation from -40°C to +125°C (Grade 1). ESD protection exceeds 2000V HBM and 1000V CDM per AEC-Q100 standards.

Feature Summary

• Automotive Grade 1 qualification compliant with AEC-Q100 standards
• Schmitt trigger action on all inputs for improved noise immunity
• High ESD protection exceeding 2000V Human Body Model
• Totally lead-free and fully RoHS compliant construction

Applications

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

Procurement Notes

Verify the component meets AEC-Q100 Grade 1 requirements for your specific application environment. Confirm that the SOT25 package variant matches your PCB footprint design. Ensure input signals remain within the specified voltage limits to maintain proper logic levels. Check datasheet thermal resistance values if operating near maximum temperature ratings.

Selection Notes

Select this part when a single-channel buffer with high-speed switching and robust automotive durability is required. The AHCT family ensures compatibility with standard CMOS logic levels while offering higher drive capability than standard LVC devices. Consider the 3-state output functionality for bus-oriented designs where multiple drivers share a common line.

Part Context

This component belongs to the 74AHCT1GxxQ series of single-gate logic devices designed for automotive environments. It shares the same logical function as other members in the 74AHCT1G125 family but includes specific automotive qualification markings. The 'Q' suffix indicates AEC-Q100 compliance, distinguishing it from standard commercial grade counterparts.

Replacement Considerations

Direct substitutes include other AEC-Q100 qualified single buffers such as the 74AHCT1G125SE-7 (SOT353 package) or equivalent parts from other manufacturers meeting the same electrical specifications and automotive standards.
