74LVC1G125GV-Q100125

Overview

The Nexperia 74LVC1G125GV-Q100 is a single non-inverting bus buffer and line driver featuring three-state outputs, 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 an ambient temperature range from -40 °C to +125 °C. The device incorporates Schmitt-trigger inputs for noise immunity and includes IOFF circuitry to prevent backflow current during partial power-down states. It meets AEC-Q100 Grade 1 qualification standards for automotive applications.

Feature Summary

• Features integrated IOFF circuitry that disables outputs to prevent damaging backflow currents when the device is powered down.
• Includes Schmitt-trigger action at all inputs to provide tolerance against slower input rise and fall times.
• Provides direct interface compatibility with TTL logic levels while supporting mixed 3.3 V and 5 V environments.

Applications

• Automotive electronic systems requiring AEC-Q100 Grade 1 qualified components
• Mixed-signal translation between 3.3 V and 5 V logic domains
• Partial power-down mode operation in portable or battery-powered equipment

Procurement Notes

Verify the specific ordering suffix GV corresponds to the SC-74A (SOT753) package configuration required for your design. Confirm that the AEC-Q100 Grade 1 qualification aligns with your project's automotive reliability specifications. Ensure the operating temperature range up to +125 °C meets your environmental constraints before finalizing procurement.

Selection Notes

Select this component when a single-channel, non-inverting buffer with three-state control is needed for high-noise environments. The inclusion of Schmitt triggers makes it suitable for signals with slow transition rates. Verify that the SC-74A footprint matches your PCB layout requirements and that the 1.65 V to 5.5 V supply range covers your system's voltage rails.

Part Context

This part belongs to the 74LVC1G125-Q100 family of single bus buffers. Other variants in the series include the GW version in TSSOP5, the GM version in XSON6, and the GZ version in XSON5. All share identical electrical characteristics but differ in physical package dimensions and terminal configurations.

Replacement Considerations

Direct substitutes within the same family include 74LVC1G125GW-Q100, 74LVC1G125GM-Q100, and 74LVC1G125GZ-Q100. These alternatives offer identical electrical performance but utilize different packages such as TSSOP5, XSON6, or XSON5. Cross-package replacement requires verifying mechanical fit and pinout compatibility.
