74LVC1G125FW5-7

Overview

The 74LVC1G125FW5-7 is a single non-inverting buffer and bus driver manufactured by Diodes Incorporated, featuring a 3-state output. It operates within a supply voltage range of 1.65V to 5.5V and utilizes the X1-DFN1010-6 (Type B) package with a 5000-unit tape and reel quantity. The device supports partial power-down applications through integrated I_OFF circuitry, which disables the output to prevent damaging current backflow when the device is powered down. Inputs are tolerant to 5.5V, enabling direct interface with TTL levels in mixed-voltage environments.

Feature Summary

• Provides a single-channel non-inverting buffer function with high-impedance state control via an active-low Output Enable pin.
• Incorporates dedicated I_OFF circuitry that automatically isolates the output during partial power-down conditions to prevent reverse current flow.
• Features input tolerance up to 5.5V, allowing safe operation and direct interfacing with TTL logic levels across varying supply voltages.

Applications

• Voltage level shifting between different logic domains
• General purpose logic buffering
• Power down signal isolation

Procurement Notes

Verify the specific FW5 suffix corresponds to the X1-DFN1010-6 Type B package configuration before procurement. Confirm that the 5000-unit tape and reel packing matches the production requirements. Ensure design compatibility with the specified operating temperature range and verify that the 5.5V input tolerance aligns with the target system's voltage levels.

Selection Notes

Select this component for designs requiring a compact single-buffer solution with robust protection against backflow currents. The wide supply voltage range accommodates both low-power and standard logic systems. Consider the X1-DFN1010-6 footprint constraints and ensure the PCB layout adheres to the manufacturer's suggested pad dimensions for optimal thermal and electrical performance.

Part Context

This part belongs to the 74LVC1G125 series of single buffers with 3-state outputs from Diodes Incorporated. The FW5 ordering suffix specifically denotes the X1-DFN1010-6 (Type B) surface-mount package. This series is designed for portable and general-purpose electronics requiring efficient signal buffering with minimal power consumption and high noise immunity.

Replacement Considerations

Consult official documentation for verified substitutes such as the 74LVC1G125W5-7 or 74LVC1G125SE-7. Verify package compatibility and pin assignments before substituting components to ensure proper integration into existing layouts.
