74LVC1G125GW,165

Overview

The Nexperia 74LVC1G125GW,165 is a single bus buffer and line driver featuring a 3-state output. It operates within a supply voltage range of 1.65 V to 5.5 V and utilizes Schmitt-trigger inputs for noise immunity. The device includes IOFF circuitry to prevent backflow current during partial power-down states. It is housed in a TSSOP5 (SOT353-1) package with five leads.

Feature Summary

• Provides non-inverting buffering with high noise immunity via Schmitt-trigger inputs
• Supports mixed-voltage environments by accepting 3.3 V or 5 V input signals
• Includes IOFF circuitry to disable outputs and prevent damaging backflow currents when powered down

Applications

• Translating signals between mixed 3.3 V and 5 V logic systems
• Driving high-capacitance or long transmission lines as a line driver
• Managing data buses requiring controlled 3-state output enablement

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm the exact package type and temperature rating. Ensure the requested variant matches the required lead configuration and thermal specifications for your design.

Selection Notes

Select this component when a single-channel buffer with 3-state control is needed for low-voltage applications. Consider the TSSOP5 package constraints and verify that the input transition rates comply with the specified limits for the chosen supply voltage.

Part Context

This part belongs to the 74LVC family of CMOS logic devices designed for low-voltage operation. The 74LVC1G125 series offers various package options including XSON and SC-74A, providing flexibility for space-constrained designs while maintaining compatibility with standard logic levels.

Replacement Considerations

Check for direct substitutes such as the 74LVC1G126, which shares similar electrical characteristics but features active-low output enable logic instead of active-high.
