MC74ACT125M

Overview

The MC74ACT125M is a quad buffer and line driver manufactured by onsemi, belonging to the 74ACT logic series. It features four non-inverting channels with three-state outputs housed in a 14-pin SOIC package. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical specifications include a propagation delay of 9 ns at 5 V, high-level output current of -24 mA, low-level output current of 24 mA, and static current of 8 uA. It supports surface mount installation and functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides four independent non-inverting buffer channels for signal conditioning
• Features three-state outputs allowing direct connection to bus-oriented systems
• Designed for high-speed digital applications with low propagation delay
• Compatible with standard CMOS and LSTTL input levels

Applications

• Memory address drivers in computer systems

Procurement Notes

Verify the specific suffix 'M' against the official datasheet to confirm package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements if applicable to your assembly process. Cross-reference the manufacturer part number with authorized distributors to confirm availability and authenticity. Check for any automotive or industrial qualification markings if required for your specific application environment.

Selection Notes

Select this component when a quad non-inverting buffer with three-state capability is required for 5V CMOS logic systems. It is suitable for designs needing high drive strength and fast switching speeds. Consider the 14-pin SOIC package for surface mount PCB layouts. Verify that the 4.5V to 5.5V supply voltage range aligns with your system power rails before finalizing the design.

Part Context

This part belongs to the 74ACT family of high-speed CMOS logic devices. It serves as a buffer and line driver, offering improved performance over older LS series counterparts. The device is designed for use in memory address drivers, clock drivers, and other bus-oriented applications requiring reliable signal transmission and isolation.

Replacement Considerations

Check for compatible parts such as MC74ACT125DR2G or MC74ACT125DTR2G which share similar functional characteristics. Ensure pinout compatibility and electrical specifications match before substitution. Verify package dimensions and thermal requirements for alternative sources.
