MC74ACT125ML2

Overview

The MC74ACT125ML2 is a quad buffer and line driver from the 74ACT logic family, manufactured by Motorola. It features four non-inverting channels with three-state outputs, housed in a 14-SOIC surface-mount package. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a propagation delay of 9 ns at 5 V, high-level output current of -24 mA, and low-level output current of 24 mA. Static current is specified at 8 uA, with a maximum operating temperature of +85 C.

Feature Summary

• Provides four independent non-inverting buffer channels for signal conditioning
• Features three-state outputs allowing bus-oriented connections
• Operates on standard 5V CMOS logic levels

Applications

• Bus-oriented systems requiring signal buffering
• Clock distribution networks
• Memory address/data bus drivers

Procurement Notes

Verify the manufacturer origin carefully, as this component was originally produced by Motorola before its semiconductor division became onsemi. Confirm the specific suffix 'ML2' corresponds to the 14-SOIC package variant. Ensure compatibility with existing design specifications regarding pinout and electrical characteristics when sourcing from different distributors or legacy stock.

Selection Notes

Select this component for applications requiring robust 5V buffering with high drive capability. The ACT series offers speed comparable to LS TTL but with CMOS power consumption. Consider the 14-SOIC package for surface-mount assembly requirements. Verify that the three-state control signals are compatible with the system's logic levels to prevent bus contention.

Part Context

This part belongs to the 74ACT family of high-speed CMOS logic devices. It serves as a direct replacement for older 74LS125 components in many designs, offering improved switching speeds while maintaining compatibility with standard 5V logic interfaces. The device is widely used in digital communication and computing hardware.

Replacement Considerations

The MC74ACT125DTR2G from onsemi is a verified substitute part number for this component, sharing identical logical functions and electrical specifications.
