74LVC1G125FZ4-7

Overview

The 74LVC1G125FZ4-7 is a single non-inverting buffer with 3-state output from Diodes Incorporated, operating within a 1.65V to 5.5V supply range. It utilizes the X2-DFN1410-6 package and features inputs tolerant up to 5.5V for mixed-voltage environments. The device supports partial power-down applications via integrated IOFF circuitry, which disables outputs to prevent damaging backflow currents when powered down.

Feature Summary

• Integrated IOFF circuitry prevents damaging current backflow during partial power-down states
• Inputs accept voltages up to 5.5V, enabling direct interface in mixed-voltage systems
• Provides high ESD protection exceeding specified thresholds for machine, human body, and charged device models

Applications

• Voltage level shifting between different logic domains
• Power down signal isolation in multi-supply architectures
• General purpose buffering for portable computing devices and peripherals

Procurement Notes

Verify the specific FZ4 suffix corresponds to the X2-DFN1410-6 package configuration before integration. Confirm that the design accommodates the required thermal resistance characteristics for the selected mounting environment. Ensure input signals remain within the absolute maximum ratings to maintain device reliability and compliance with RoHS directives.

Selection Notes

Select this component when a single-channel buffer with controlled high-impedance states is required for low-voltage digital interfaces. The wide supply voltage compatibility allows operation across standard logic families. Consider the specific pinout of the X2-DFN1410-6 package for PCB layout optimization compared to alternative package options like SOT25 or X2-DFN1409-6.

Part Context

This part belongs to the 74LVC1G series of single-gate logic devices manufactured by Diodes Incorporated under the LVC logic family. It is designed for low-power CMOS applications requiring robust performance across varying temperature ranges. The device represents a compact solution for signal conditioning and bus driving in space-constrained electronic designs.

Replacement Considerations

Direct substitutes include other packages within the same function family such as 74LVC1G125FX4-7 (X2-DFN1409-6) or 74LVC1G125FW4-7 (X2-DFN1010-6). Verify pin compatibility and thermal characteristics when substituting between different package types within the same logical function.
