MC74VHC125D

Overview

The MC74VHC125D is a quad non-inverting buffer and line driver manufactured by onsemi. It operates within a supply voltage range of 2.0 V to 5.5 V and features four independent channels with three-state outputs. The device utilizes CMOS technology for low power consumption and high noise immunity. It is housed in a standard SOIC-14 surface-mount package, suitable for space-constrained designs requiring signal buffering or line driving capabilities.

Feature Summary

• Provides four independent non-inverting buffer channels
• Features three-state output capability for bus-oriented applications
• Operates across a wide supply voltage range from 2.0 V to 5.5 V

Applications

• Bus-oriented systems requiring signal isolation
• Clock distribution networks
• Memory address decoding circuits

Procurement Notes

Verify the specific suffix 'D' corresponds to the SOIC-14 package configuration when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the component meets the required operating temperature specifications for the intended application environment.

Selection Notes

Select this component for applications requiring multiple buffered signals in a compact form factor. The wide voltage tolerance supports both 3.3 V and 5 V logic interfaces. Consider the propagation delay characteristics relative to system timing requirements during the design phase.

Part Context

This part belongs to the 74VHC series of high-speed CMOS logic devices. It serves as a buffer solution within digital logic families, offering improved switching speeds compared to older standards while maintaining compatibility with standard logic levels.

Replacement Considerations

Check for pin-compatible alternatives such as the MC74VHC125DT or variants from other manufacturers like NXP or Texas Instruments that match the SOIC-14 footprint and electrical specifications.
