CD74ACT541E

Overview

The CD74ACT541E 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 DIP package. The device operates within a supply voltage range of 4.5 V to 5.5 V. It provides three-state outputs with high-level output currents of -24 mA and low-level output currents of 24 mA. The component supports a wide operating temperature range from -55°C to +125°C.

Feature Summary

• Octal configuration providing eight independent non-inverting signal paths
• Three-state output capability for effective bus line driving and isolation
• Robust drive strength supporting high capacitive loads on transmission lines

Applications

• Bus-oriented architectures requiring signal buffering
• Clock distribution networks for timing signals
• Memory address decoding and data register interfaces

Procurement Notes

Verify the specific suffix 'E' corresponds to the standard plastic DIP-20 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets, as environmental declarations may vary by production batch. Ensure the ordering part number matches the exact pinout and electrical specifications required for the target circuit design.

Selection Notes

Select this component for designs requiring high-speed CMOS performance with significant current drive capabilities. The ACT series offers faster propagation delays compared to legacy HC families while maintaining compatibility with standard TTL logic levels. Consider the DIP-20 package for prototyping or applications necessitating through-hole mounting on printed circuit boards.

Part Context

This integrated circuit is part of the broader 74ACT logic family, designed to bridge the performance gap between older AC/ACT technologies and newer low-voltage standards. It serves as a fundamental building block for digital systems requiring reliable signal amplification and direction control across multiple parallel data lines.
