74AHCT1G02QSE-7

Overview

The 74AHCT1G02QSE-7 is a single 2-input positive NOR gate from the AHCT logic family, designed for automotive applications. 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 supports ambient temperature operation from -40°C to +125°C (Grade 1). Propagation delay is specified as 4.9ns typical at VCC=5V with a 50pF load. It includes Schmitt trigger inputs for tolerance to slower rise/fall times and offers ESD protection exceeding 2000V HBM.

Feature Summary

• Automotive Grade 1 qualification compliant with AEC-Q100 standards
• Schmitt trigger action on all inputs for improved noise immunity
• Totally lead-free and fully RoHS compliant construction
• Balanced propagation delays and symmetric drive capability

Applications

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

Procurement Notes

Verify that the ordering suffix 'SE' corresponds specifically to the SOT353 package variant required for your design. Confirm that the '-7' suffix indicates the standard 7-inch tape and reel packaging format containing 3000 units per reel. Ensure compatibility with IATF 16949 certified manufacturing facilities if specific change control protocols are mandated by your procurement specifications.

Selection Notes

Select this component when a single 2-input NOR function is required in an AHCT logic environment. It is suitable for designs needing robust performance across wide temperature ranges and high ESD tolerance. Verify that the 4.5V to 5.5V operating voltage aligns with your system power rails. Consider the SOT353 package dimensions against available PCB real estate constraints during the layout phase.

Part Context

This part belongs to the 74AHCT1G series of single-function gates manufactured by Diodes Incorporated. The AHCT family ensures TTL-compatible input levels while maintaining CMOS low-power consumption characteristics. The 'Q' designation signifies automotive qualification, distinguishing it from standard commercial grade devices within the broader logic portfolio.

Replacement Considerations

The 74AHCT1G02QW5-7 serves as a functional substitute utilizing the SOT25 package instead of SOT353. Both variants share identical electrical characteristics and logic functions but differ in physical footprint and pin pitch dimensions.
