74AHC1G125QSE-7

Overview

The 74AHC1G125QSE-7 is an automotive-compliant single non-inverting buffer and bus driver with a 3-state output, manufactured by Diodes Incorporated. 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 provides ±8mA output drive at 4.5V and features Schmitt trigger action at all inputs for tolerance to slower input rise and fall times. Inputs are not limited by VCC, ensuring balanced propagation delays and drive capability. It includes ESD protection exceeding 2000-V Human Body Model and 1000-V Charged Device Model per AEC-Q100 standards.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 standards and PPAP capable for specific change control requirements.
• Schmitt trigger inputs provide circuit tolerance for slower input rise and fall times while maintaining balanced propagation delays.
• Outputs enter a high-impedance state when the Output Enable (OE) pin receives a HIGH-level signal.

Applications

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

Procurement Notes

Verify that the component meets AEC-Q100 Grade 1 qualification requirements for automotive use. Confirm the package type matches the SOT353 specification and ensure compliance with IATF 16949 manufacturing standards. Check RoHS 3 and halogen-free status against project specifications before finalizing procurement orders.

Selection Notes

Select this component for designs requiring a single-channel buffer with 3-state control in space-constrained PCB layouts. It is suitable for replacing standard logic buffers where automotive reliability and wide operating voltage ranges are necessary. Ensure input signals do not exceed absolute maximum ratings to prevent latch-up or damage during operation.

Part Context

This part belongs to the 74AHC1GxxQ series of single-gate logic devices designed for automotive and industrial markets. It shares the AHC logic family characteristics, offering CMOS low-power consumption and compatibility with standard digital interfaces. The 'Q' suffix indicates automotive qualification, while 'SE' denotes the SOT353 surface-mount package.

Replacement Considerations

The 74AHC1G125QW5-7 serves as a direct functional substitute using the SOT25 package instead of SOT353. Both parts share identical electrical characteristics and automotive qualifications. Verify footprint compatibility when swapping between these package variants.
