CD74ACT541E

Overview

The CD74ACT541E is an octal buffer and line driver manufactured by Harris Corporation, belonging to the ACT logic series. It features eight non-inverting outputs with three-state capability, housed in a 20-pin DIP 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 8.2 ns at 4.5 V to 5.5 V, output currents of ±24 mA, and a static current of 8 µA. It supports a wide operating temperature range from -55 °C to +125 °C.

Feature Summary

• Provides eight non-inverting buffered channels for signal driving applications
• Features three-state outputs allowing direct connection to bus structures
• Utilizes CMOS technology for low power consumption and high noise immunity

Applications

• High-performance register buffering
• Clock distribution circuits
• Memory address drivers

Procurement Notes

Verify the manufacturer origin as Harris Corporation, noting that this entity has undergone corporate changes affecting product lines. Confirm the specific suffix 'E' corresponds to the standard plastic DIP-20 package configuration. Ensure compatibility with existing board layouts requiring through-hole mounting and verify that the ACT series specifications meet the system's timing and voltage requirements.

Selection Notes

Select this component when designing systems requiring robust octal buffering with three-state control. The ACT series offers a balance of speed and drive strength suitable for general-purpose digital interfaces. Consider the extended industrial temperature range if the application involves harsh environmental conditions. Ensure the design accommodates the 20-pin DIP footprint and the specific pinout configuration defined for the ACT541 family.

Part Context

This component is part of the broader 74ACT541 family of octal buffers. While originally produced by Harris Corporation, similar devices are now widely available from other semiconductor manufacturers such as Texas Instruments under the CD74ACT541 designation. The functional characteristics remain consistent across manufacturers within the same logic family specification.

Replacement Considerations

Texas Instruments CD74ACT541N serves as a verified equivalent offering identical functionality and pinout compatibility.
