MC74LVX125D

Overview

The MC74LVX125D is a quad buffer and line driver from the onsemi LVX logic family, designed for low-voltage CMOS applications. It operates within a supply voltage range of 2 V to 3.6 V and features four non-inverting channels with three-state outputs. The device utilizes a 14-pin SOIC package and supports surface-mount installation. Key electrical characteristics include a maximum static current of 4 uA and output drive capabilities of 4 mA at both high and low states. It functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Provides four independent non-inverting buffer channels with three-state output control for bus-oriented communication systems.
• Operates efficiently at low supply voltages ranging from 2 V to 3.6 V, suitable for portable and battery-powered designs.
• Features low static power consumption and robust ESD protection compatible with CMOS standards.

Applications

• Bus-oriented memory and data transmission architectures requiring signal buffering.
• Clock distribution networks in low-voltage digital systems.
• Portable consumer electronics utilizing 3.3 V or 2.5 V logic levels.

Procurement Notes

Verify the specific suffix 'D' corresponds to the SOIC-14 package configuration required for your PCB layout. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the component meets the thermal requirements of your intended operating environment, specifically the -40°C to +85°C range. Cross-reference the ordering part number with the latest datasheet revision to avoid obsolete variants.

Selection Notes

Select this component when designing circuits that require low-voltage operation between 2 V and 3.6 V with minimal power consumption. It is appropriate for applications needing four buffered signals with tri-state capability for bus sharing. Consider the SOIC-14 package constraints regarding board space and thermal dissipation. Compare propagation delay specifications against system timing requirements to ensure signal integrity is maintained.

Part Context

This component belongs to the 74LVX125 series, which represents low-voltage CMOS technology optimized for performance and power efficiency. The LVX family bridges the gap between standard 5 V TTL compatibility and modern low-voltage logic standards. It serves as a fundamental building block for signal conditioning in mixed-voltage environments common in contemporary electronic devices.

Replacement Considerations

Check for direct pin-compatible alternatives within the same LVX family, such as the MC74LVX125DTG or MC74LVX125DTR2G, which may offer different packaging options like TSSOP or tape-and-reel formats. Verify that any substitute maintains the same 2 V to 3.6 V operating voltage and 14-pin footprint.
