CD74ACT541MG4

Overview

The CD74ACT541MG4 is an octal buffer and line driver manufactured by Texas Instruments, belonging to the 74ACT logic family. It features eight non-inverting channels with three-state outputs, designed for high-speed digital applications. The device operates within a supply voltage range of 4.5V to 5.5V and utilizes CMOS technology. It is housed in a 20-pin Small Outline Package (SOIC) suitable for surface-mount assembly. The component supports output drive currents of 24mA at both high and low states, ensuring robust signal integrity across various industrial and commercial environments.

Feature Summary

• Provides eight independent non-inverting buffering channels for signal isolation and distribution
• Features three-state outputs allowing multiple drivers to share bus lines without interference
• Utilizes advanced CMOS technology to achieve high switching speeds with low power consumption
• Operates reliably across extended temperature ranges suitable for demanding industrial applications

Applications

• High-speed data bus buffering in computer systems
• Clock distribution networks requiring precise signal timing
• Memory module interface circuits for data storage devices
• Industrial control systems managing complex digital signals

Procurement Notes

Verify the specific package variant and tape-and-reel specifications against the official datasheet before ordering. Confirm that the manufacturing site and RoHS compliance status meet your project requirements. Ensure compatibility with existing PCB footprints and soldering profiles. Cross-reference the full part number including the suffix to avoid discrepancies in lead frame material or moisture sensitivity levels.

Selection Notes

Select this component when designing circuits requiring octal buffering with tri-state capability. It is appropriate for systems operating strictly at 5V logic levels. Consider the SOIC-20 footprint constraints during layout planning. Evaluate propagation delay characteristics against system clock speeds to ensure timing margins are sufficient for reliable operation under worst-case conditions.

Part Context

This device is part of the broader 74ACT series, which bridges the performance gap between older TTL standards and modern AC logic families. It shares functional similarities with other octal buffers like the SN74ACT541 but may differ in packaging options such as TSSOP or VQFN. The MG4 suffix typically indicates a specific tape-and-reel configuration and environmental compliance standard defined by the manufacturer.

Replacement Considerations

Direct substitutes include the SN74ACT541N and SN74ACT541PW. Verify pinout compatibility and electrical parameters before swapping. Alternative packages like TSSOP-20 offer space savings but require different footprints.
