CD74ACT541M

Overview

The CD74ACT541M is an octal buffer and line driver manufactured by Texas Instruments, belonging to the 74ACT logic family. It features eight non-inverting inputs and outputs housed in a 20-pin SOIC package. The device operates within a supply voltage range of 4.5 V to 5.5 V. It provides high drive capability with output currents of -24 mA for high state and 24 mA for low state. The component supports three-state outputs and functions reliably across an extended temperature range from -55°C to +125°C.

Feature Summary

• Octal configuration providing eight independent non-inverting signal paths
• Three-state output architecture enabling bus-oriented system designs
• High current drive capability suitable for direct interface to CMOS, NMOS, and TTL loads

Applications

• Bus-oriented architectures requiring signal buffering
• Memory and memory mapping applications
• Clock distribution and buffering circuits

Procurement Notes

Verify the specific suffix designation against official documentation, as variations such as M96 indicate distinct packaging formats like cut tape or reel. Confirm that the selected variant matches the required pinout and thermal specifications for the target application environment. Ensure compliance with RoHS directives if applicable to the manufacturing region.

Selection Notes

Select this component when an octal buffer with three-state control is required for 5 V systems. The ACT series offers faster switching speeds compared to standard 74LS equivalents while maintaining compatible pinouts. Consider the wide operating temperature range for industrial environments and the robust drive strength for driving multiple loads on shared data lines.

Part Context

This part belongs to the Texas Instruments 74ACT series of advanced CMOS logic devices. The 74ACT541 variant specifically serves as an octal buffer with three-state outputs. It is designed to replace older 74LS technology in high-speed applications, offering improved performance metrics while retaining electrical compatibility with legacy systems.

FAQ

What is the polarity of the CD74ACT541M?

The device is a non-inverting buffer, meaning the output signals follow the input states directly without logical inversion.

Does the CD74ACT541M support bidirectional data flow?

No, it is a unidirectional buffer. Data flows only from the inputs to the outputs.
