74AHCT1G02QW5-7

Overview

The 74AHCT1G02QW5-7 is a single, two-input positive NOR gate from the 74AHCT logic family. 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 includes Schmitt trigger action at all inputs for tolerance to slower input rise and fall times. It is designed for ambient temperature operation from -40°C to +125°C.

Feature Summary

• AEC-Q100 Grade 1 qualified for automotive applications requiring specific change control
• Schmitt trigger inputs provide circuit tolerance for slower input transition rates
• Totally lead-free, fully RoHS compliant, and halogen/antimony free

Applications

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

Procurement Notes

Verify that the component matches the exact Diodes Incorporated part number 74AHCT1G02QW5-7. Confirm the SOT25 package code W5 and the -7 tape and reel suffix. Ensure the supplier source aligns with authorized distribution channels to guarantee AEC-Q100 qualification and IATF 16949 manufacturing compliance.

Selection Notes

Select this component when a single-channel NOR function is required in 5V CMOS logic environments. The AHCT series ensures TTL-compatible input thresholds while maintaining low power consumption. The wide operating temperature range makes it suitable for harsh industrial or automotive conditions where standard commercial grade parts may fail.

Part Context

This device belongs to the 74AHCT1GxxQ series of automotive-compliant single-gate logic devices. It shares the same pinout and electrical characteristics as other members of the family but implements the NOR logic function. The Q suffix indicates AEC-Q100 qualification, distinguishing it from non-automotive variants.

Replacement Considerations

Direct substitutes include other 74AHCT1G02 variants from different manufacturers, provided they support the SOT25 package and meet the 4.5V to 5.5V supply requirements. Verify that any replacement also meets AEC-Q100 Grade 1 specifications if automotive qualification is mandatory.
