74LVC1G125GV-Q100,

Overview

The Nexperia 74LVC1G125GV-Q100 is a single buffer and line driver featuring a three-state output, housed in the SC-74A (SOT753) surface-mount package. It operates within a supply voltage range of 1.65 V to 5.5 V and supports overvoltage tolerant inputs up to 5.5 V. The device includes Schmitt-trigger action for noise immunity and IOFF circuitry for partial power-down applications. Qualified to AEC-Q100 Grade 1 standards, it functions reliably from -40 °C to +125 °C.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• IOFF circuitry enables partial power-down mode operation
• Schmitt-trigger inputs provide tolerance for slow signal transitions
• Overvoltage tolerant inputs allow direct interfacing with 5 V devices

Applications

• Mixed 3.3 V and 5 V bus buffering environments
• Partial power-down system configurations
• Automotive electronic circuits requiring Grade 1 qualification

Procurement Notes

Verify the specific ordering suffix GV corresponds to the SC-74A package when sourcing. Confirm that the Q100 designation ensures compliance with automotive reliability requirements. Check the latest datasheet revision for any updates to pinning or electrical characteristics before finalizing procurement specifications.

Selection Notes

Select this component for designs requiring a single-channel buffer with high noise immunity and automotive grade reliability. The wide supply voltage range facilitates integration into mixed-voltage systems. Ensure the SC-74A package dimensions fit the available PCB space constraints.

Part Context

This part belongs to the 74LVC1G125-Q100 family of single buffers with three-state outputs. Other variants in the series include the GW (TSSOP5), GM (XSON6), and GZ (XSON5) packages, all sharing identical electrical performance but differing in physical footprint and lead configuration.

Replacement Considerations

Direct substitutes include other 74LVC1G125 variants from different manufacturers that match the SC-74A package and AEC-Q100 Grade 1 qualification. Verify pinout compatibility and electrical parameters such as propagation delay and output drive current.
