74AHC1G125QW5-7

Overview

The 74AHC1G125QW5-7 is an automotive-compliant single non-inverting buffer/bus driver with a 3-state output manufactured by Diodes Incorporated. It operates within a power supply 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, balanced propagation delays, and ±8mA output drive capability at 4.5V. It is housed in a SOT25 package and includes ESD protection exceeding 2000V (HBM) and 1000V (CDM).

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 standards for reliability.
• Schmitt trigger action on all inputs ensures tolerance for slower input rise and fall times.
• Outputs enter a high-impedance state when the Output Enable (OE) pin receives a HIGH-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

Procurement Notes

Verify that the specific part number suffix matches the required package type, as the Q series is available in both SOT25 and SOT353 configurations. Confirm compliance requirements such as RoHS and halogen-free status directly against the manufacturer's documentation. Ensure the application environment stays within the specified operating temperature range of -40°C to +125°C for proper functionality.

Selection Notes

Select this component when a single-channel, non-inverting buffer with 3-state control is required for automotive or industrial logic circuits. It is suitable for designs needing Schmitt trigger input noise immunity and operation across a wide voltage range from 2.0V to 5.5V. Consider the SOT25 package dimensions if space constraints align with its footprint specifications.

Part Context

This component belongs to the 74AHC1G125Q family of single-buffer gates with 3-state outputs. It is designed for general-purpose logic applications requiring robust performance in demanding environments. The 'Q' designation indicates AEC-Q100 qualification, while the 'W5' suffix specifically identifies the SOT25 surface-mount package variant.

Replacement Considerations

The datasheet lists the SOT353 variant, 74AHC1G125QSE-7, as a package alternative within the same functional family. No other cross-manufacturer substitutes are documented in the provided source material.

FAQ

How does the Output Enable (OE) pin affect the output state?

The output enters a high-impedance state when a HIGH-level signal is applied to the OE pin.

What is the maximum operating junction temperature?

The absolute maximum rating for the operating junction temperature is +150°C, though the recommended operating free-air temperature extends up to +125°C.
