74AHC1G02QSE-7

Overview

The 74AHC1G02QSE-7 is an automotive-compliant single two-input positive NOR gate manufactured by Diodes Incorporated. It operates within a supply voltage range of 2.0V to 5.5V and features standard push-pull outputs with ±8mA drive capability at 4.5V. The device incorporates Schmitt trigger inputs for tolerance to slower signal transitions and balanced propagation delays. It is housed in a SOT-353 package, supports ambient temperature operation from -40°C to +125°C, and includes ESD protection exceeding 2000V HBM.

Feature Summary

• Automotive Grade 1 qualification with AEC-Q100 standards and PPAP capability
• Schmitt trigger inputs provide circuit tolerance for slow rise and fall times
• Inputs are not limited by VCC voltage levels
• Totally lead-free, 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 machinery

Procurement Notes

Verify the specific ordering suffix 'SE' corresponds to the SOT-353 package configuration required for your design. Confirm that the '-7' suffix aligns with the specified tape and reel quantity. Ensure the component meets the necessary IATF 16949 certification requirements if utilized in automotive supply chains. Cross-reference the datasheet revision to confirm current manufacturing status.

Selection Notes

Select this component when a single NOR function is required in space-constrained designs utilizing the SOT-353 footprint. It is suitable for systems requiring robust noise immunity due to Schmitt trigger inputs. Consider its wide operating voltage range for interfacing with various logic families. Verify thermal resistance characteristics against your PCB layout constraints.

Part Context

This part belongs to the 74AHC1G series of high-speed CMOS logic devices. The 'Q' designation indicates automotive compliance, distinguishing it from standard commercial variants. It serves as a fundamental building block for digital logic circuits, providing Boolean NOR functionality in a compact surface-mount package suitable for automated assembly processes.

Replacement Considerations

The 74AHC1G02W5-7 is a confirmed substitute offering identical electrical performance but packaged in SOT-25 instead of SOT-353.
