74LVC1G125GW-Q100,

Overview

The Nexperia 74LVC1G125GW-Q100 is a single non-inverting bus buffer and line driver featuring a 3-state output, housed in a TSSOP5 (SOT353-1) plastic package. It operates within a supply voltage range of 1.65 V to 5.5 V and supports an input voltage up to 5.5 V. The device includes Schmitt-trigger inputs for noise immunity and IOFF circuitry for partial power-down protection. Qualified to AEC-Q100 Grade 1 standards, it functions reliably across ambient temperatures from -40 °C to +125 °C.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standard
• IOFF circuitry prevents damaging backflow current during partial power-down
• Schmitt-trigger action provides tolerance for slow input rise and fall times
• Direct interface capability with TTL logic levels

Applications

• Mixed 3.3 V and 5 V signal translation environments
• Partial power-down mode applications requiring backflow prevention
• Automotive electronic systems

Procurement Notes

Verify the specific ordering suffix 'GW' corresponds to the SOT353-1 (TSSOP5) package variant. Confirm that the required temperature grade matches the specified -40 °C to +125 °C operational range. Ensure the application design accounts for the AEC-Q100 Grade 1 qualification status when integrating into automotive circuits.

Selection Notes

Select this component when a single-channel buffer with 3-state control is required for mixed-voltage interfaces. The wide supply range accommodates both low-power and standard logic families. The inclusion of Schmitt triggers makes it suitable for noisy environments or signals with slow transitions.

Part Context

This part belongs to the 74LVC1G125-Q100 family of single bus buffers. Other variants in the series include the GV (SC-74A), GM (XSON6), and GZ (XSON5) packages, offering different form factors while maintaining identical electrical specifications and automotive qualifications.

Replacement Considerations

Substitutes must match the 74LVC1G125 function code and maintain AEC-Q100 Grade 1 qualification. Verify pinout compatibility between the TSSOP5 package and the target footprint. Ensure replacement devices support the same 1.65 V to 5.5 V supply range and 3-state output behavior.
