74AHC1G126QW5-7

Overview

The Diodes Incorporated 74AHC1G126QW5-7 is an automotive-compliant single non-inverting buffer with a 3-state output, designed for operation within a power supply range of 2.0V to 5.5V. It features Schmitt trigger inputs and balanced propagation delays. The device provides ±8mA output drive at 4.5V and operates across Grade 1 ambient temperatures from -40°C to +125°C. Packaged in SOT25, it includes ESD protection exceeding 2000V HBM and 1000V CDM per AEC-Q100 standards.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 standards
• Schmitt trigger action on all inputs for tolerance to slower rise and fall times
• Outputs enter high impedance state when Output Enable (OE) pin receives LOW-level signal
• Inputs are not limited by VCC voltage levels

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 the specific package code W5 corresponds to the SOT25 footprint required for your PCB layout. Confirm that the Q suffix indicates AEC-Q100 qualification if automotive compliance is mandatory for your design. Ensure the OE pin logic polarity matches your system's enable requirements, as the device activates on HIGH level input.

Selection Notes

Select this component when a single-channel, non-inverting buffer with controlled output enable is needed in a compact surface-mount form factor. The wide operating voltage range supports both low-power 2V and standard 5V logic interfaces. Consider the Schmitt trigger feature if input signals exhibit slow transitions or noise susceptibility.

Part Context

This part belongs to the 74AHC1G series of single-gate logic devices manufactured by Diodes Incorporated. The 'Q' designation signifies automotive qualification, while 'W5' identifies the SOT25 package variant. It is part of a broader family including similar buffers and drivers optimized for space-constrained electronic designs.

Replacement Considerations

Direct substitutes include other 74AHC1G126 variants from different manufacturers offering identical logical functionality and pinouts. Verify that any replacement maintains the same SOT25 package dimensions and electrical characteristics, particularly the 3-state output behavior and Schmitt trigger input specifications.
