74LVC2G125HK3-7

Overview

The Diodes Incorporated 74LVC2G125HK3-7 is a dual buffer gate with 3-state outputs designed for operation over a power supply range of 1.65V to 5.5V. It features IOFF circuitry that disables the output to prevent damaging current backflow during partial power-down applications. The device accepts inputs up to 5.5V and includes Schmitt trigger action at all inputs, providing tolerance for slower input rise and fall times. ESD protection exceeds JESD 22 standards, offering 2000-V Human Body Model and over 1000-V Charged Device Model protection.

Feature Summary

• Dual buffer gate configuration with 3-state outputs
• IOFF circuitry supports partial-power-down mode operation
• Schmitt trigger action provides tolerance for slow input transitions
• Inputs accept up to 5.5V while operating on lower supply voltages

Applications

• Voltage level shifting
• General purpose logic
• Power down signal isolation

Procurement Notes

Verify the HK3 package suffix corresponds to the X2-DFN1410-8 form factor (1.35mm x 1.0mm x 0.35mm) before procurement. Confirm the -7 suffix indicates 7-inch tape and reel packaging containing 5,000 units per reel. Ensure compatibility with RoHS 2 and REACH compliance requirements for the specific manufacturing batch.

Selection Notes

Select this component when a compact dual buffer with 3-state control is required in space-constrained designs. The X2-DFN1410-8 package offers a smaller footprint compared to standard DFN options. Consider the Schmitt trigger inputs if the application involves noisy signals or slow transition rates. Verify that the 1.65V to 5.5V operating range aligns with the system's voltage rails.

Part Context

This part belongs to the 74LVC family of logic devices from Diodes Incorporated, specifically the 74LVC2G125 series. It is functionally equivalent to other manufacturers' dual buffers with 3-state outputs but utilizes Diodes' proprietary LVC technology for low voltage operation. The HK3 variant specifically denotes the X2-DFN1410-8 surface mount package.

Replacement Considerations

Direct substitutes include the 74LVC2G125HD4-7 (X2-DFN2010-8 package) and the 74LVC2G125RA3-7 (X2-DFN1210-8 package). These alternatives share identical electrical characteristics and pinouts but differ in physical dimensions and thermal resistance values.
