MC74HCT541AN

Overview

The MC74HCT541AN is an octal buffer and line driver manufactured by onsemi, belonging to the HCT logic series. It features non-inverting outputs with three-state capability, allowing for effective bus-oriented system management. The device operates within a supply voltage range of 4.5V to 5.5V and is housed in a 20-pin DIP package. Designed for TTL-level compatibility, it serves as a reliable interface between different logic families.

Feature Summary

• Provides eight non-inverting signal paths for data buffering
• Features three-state outputs to prevent bus contention
• Ensures direct compatibility with TTL logic levels

Applications

• Memory address drivers in computer systems
• Clock signal distribution networks
• Bus-oriented data transmission architectures

Procurement Notes

Verify the specific suffix 'AN' against official datasheets to confirm the through-hole DIP-20 package configuration. Ensure the order matches the required operating temperature range and that the component meets current RoHS compliance standards before finalizing procurement.

Selection Notes

Select this component when interfacing CMOS devices with TTL loads requiring high noise immunity. The HCT series ensures speed comparable to LS-TTL while maintaining low power consumption. Verify pinout compatibility with existing PCB layouts designed for standard 74-series buffers.

Part Context

This part belongs to the widely used 74HCT family of digital logic integrated circuits. These components are standard solutions for general-purpose buffering and driving applications in industrial and consumer electronics. The octal configuration allows for parallel data handling, making it essential for wide-bus systems.

Replacement Considerations

Direct substitutes include the MM74HCT541N and SN74HCT541N. Verify package dimensions and electrical characteristics match the original design requirements before swapping components.
