74LVC1G125GXH

Overview

The Nexperia 74LVC1G125GXH is a single bus buffer and line driver featuring a 3-state output, housed in an X2SON5 (SOT1226-3) package. It operates within a supply voltage range of 1.65 V to 5.5 V. The device provides ±24 mA output drive at 3.0 V and includes IOFF circuitry for partial power-down mode operation. Inputs are overvoltage tolerant up to 5.5 V and feature Schmitt-trigger action. Propagation delay ranges from 1.0 ns to 10.5 ns depending on the supply voltage.

Feature Summary

• IOFF circuitry prevents damaging backflow current during partial power-down applications
• Schmitt-trigger inputs provide tolerance for slower input rise and fall times
• Overvoltage tolerant inputs allow direct interfacing with 3.3 V or 5 V devices

Applications

• Mixed 3.3 V and 5 V environments
• Partial power down applications
• Bus-oriented transmissions

Procurement Notes

Verify the specific ordering suffix GXH corresponds to the X2SON5 package type before procurement. Confirm that the required operating temperature range aligns with the -40 °C to +125 °C specification provided in the datasheet. Ensure design compatibility with the 5-terminal configuration and verify pinout assignments against the SOT1226-3 outline drawing.

Selection Notes

Select this component when a single-channel non-inverting buffer with high noise immunity is required. The wide supply voltage range supports various logic families. The inclusion of Schmitt triggers makes it suitable for noisy environments or slow signal transitions. Verify that the thermal performance of the X2SON5 package meets the application's power dissipation requirements.

Part Context

This part belongs to the 74LVC1G125 family of single bus buffers. The 'GX' designation specifically identifies the X2SON5 plastic thermal enhanced extremely thin small outline package. This package variant offers a compact footprint with dimensions of 0.8 mm by 0.8 mm, suitable for space-constrained surface-mount designs.

Replacement Considerations

Direct replacements include other packages within the same logical family, such as 74LVC1G125GW (TSSOP5) or 74LVC1G125GV (SC-74A), provided the physical footprint and pinout differences are accommodated in the design.
