74LVC1G125QSE-7

Overview

The 74LVC1G125QSE-7 is an automotive-compliant single non-inverting buffer with a 3-state output, manufactured by Diodes Incorporated. It operates within a supply voltage range of 1.65V to 5.5V and supports Grade 1 ambient temperature operation from -40°C to +125°C. The device features IOFF circuitry for partial power-down applications, preventing damaging backflow currents. Inputs accept up to 5.5V regardless of the VCC level, facilitating mixed-voltage environments. It is AEC-Q100 qualified and PPAP capable.

Feature Summary

• AEC-Q100 qualified for Grade 1 automotive applications
• IOFF circuitry enables partial power-down mode operation
• Inputs tolerant to 5.5V for mixed-voltage compatibility
• High ESD protection exceeding 2000V Human Body Model

Applications

• Automotive applications within Grade 1 temperature range
• Voltage level shifting in mixed-voltage systems
• Power down signal isolation
• Industrial computing and controls automation

Procurement Notes

Verify that the specific part number suffix matches the required package type, as the Q series is available in both SOT353 and SOT25 configurations. Confirm compliance with IATF 16949 manufacturing standards if automotive qualification is strictly required. Ensure the design accounts for the specified operating temperature range and voltage tolerances defined in the official datasheet.

Selection Notes

Select this component when an automotive-grade buffer with high input tolerance is necessary. The 74LVC1G125Q is suitable for designs requiring partial power-down capabilities via its dedicated IOFF feature. Consider the specific package dimensions of SOT353 or SOT25 based on board space constraints. Verify that the 5.5V input tolerance aligns with the system's logic levels.

Part Context

This device belongs to the 74LVC1G125Q family, which consists of single-buffer gates designed for automotive use. The 'Q' designation indicates AEC-Q100 qualification and PPAP capability. The family includes variants with different packaging options, such as SOT353 and SOT25, all sharing the same core electrical characteristics and functional behavior.

Replacement Considerations

Direct substitutes include the standard commercial version 74LVC1G125SE-7, though it lacks automotive qualification. Other compatible buffers in the LVC family may serve as alternatives if automotive grade requirements are not mandatory.
