74AHC1G09QSE-7

Overview

The 74AHC1G09QSE-7 is an automotive-compliant, single two-input positive AND gate with an open-drain output. 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 2000V (HBM) and 1000V (CDM). It is manufactured in IATF 16949 certified facilities and is PPAP capable.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 standards
• Open-drain output configuration requiring external pull-up resistor
• Schmitt trigger action at all inputs for improved noise immunity
• High ESD protection performance exceeding specified HBM and CDM thresholds

Applications

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

Procurement Notes

Verify the specific package code against the ordering information table to ensure correct physical dimensions and lead pitch. Confirm that the application design includes the necessary external pull-up resistor required for the open-drain output stage. Ensure environmental compliance requirements match the RoHS3 and Halogen-free specifications listed in the datasheet notes.

Selection Notes

Select this component when an AND function with open-drain capability is required in space-constrained designs. The SOT353 package provides a compact footprint suitable for high-density PCB layouts. Consider the input voltage tolerance relative to the system's VCC level, as inputs are not limited by VCC. Verify thermal dissipation requirements if operating near maximum junction temperatures.

Part Context

This part belongs to the 74AHC1GxxQ series of single-gate logic devices produced by Diodes Incorporated. The 'Q' suffix indicates automotive qualification, while 'SE' denotes the SOT353 surface-mount package. It is part of a broader family including NAND, XOR, and buffer variants sharing similar electrical characteristics and packaging options.

Replacement Considerations

Direct substitutes include other AEC-Q100 qualified single AND gates with open-drain outputs in compatible packages. Verify pinout compatibility and electrical parameters such as propagation delay and output current drive before substitution.
