MC74LVX125DG

Overview

The MC74LVX125DG is a quad buffer and line driver manufactured by onsemi, belonging to the LVX logic series. It features four non-inverting channels with three-state outputs housed in a SOIC-14 package. The device operates within a supply voltage range of 2 V to 6 V. Key electrical parameters include a low-level output current of 24 mA and a high-level output current of -24 mA. Static current is specified at 8 uA, while maximum power dissipation reaches 500 mW. Propagation delay varies from 9 ns at 3.3 V to 7 ns at 5 V. The component supports surface mount installation and 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 applications.
• Operates over a wide supply voltage range from 2 V to 6 V, ensuring compatibility with various logic families.
• Delivers high drive capability with symmetric output currents of ±24 mA for robust signal transmission.
• Features low static power consumption suitable for battery-powered or energy-efficient designs.

Applications

• Bus-oriented memory and address drivers
• Clock buffering and distribution circuits
• Signal level translation between different voltage domains

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status and lead-free material declarations directly with the supplier. Check for any recent product change notifications that may affect pinout or electrical characteristics. Ensure the source distributor is authorized to guarantee component authenticity and traceability.

Selection Notes

Select this component when a quad buffer with three-state outputs is required for bus systems. The wide 2 V to 6 V operating range allows flexibility in system design compared to fixed-voltage logic families. Consider the ±24 mA output drive strength for driving moderate capacitive loads. Verify that the SOIC-14 package dimensions fit the available PCB footprint and thermal requirements.

Part Context

This part belongs to the MC74LVX125 family of quad buffers. It shares functional similarities with other LVX series devices but is distinguished by its specific voltage range and drive capabilities. The DG suffix typically denotes the SOIC-14 package variant. It serves as a standard solution for digital signal buffering in industrial and consumer electronics applications requiring reliable three-state control.

Replacement Considerations

Direct substitutes include the MC74LVX125D and MC74LVX125DTG variants, which share identical logical functionality. Cross-brand equivalents from manufacturers like NXP or Texas Instruments should be verified for pin compatibility and electrical parameter alignment before integration.
