MC74HC541AF

Overview

The MC74HC541AF is an octal 3-state non-inverting buffer and line driver manufactured by onsemi. It operates within a supply voltage range of 2 V to 6 V. The device features eight inputs and eight outputs, with a propagation delay of 80 ns at 2 V. High-level output current is -7.8 mA, and low-level output current is 7.8 mA. Static current is 4 uA. It functions in temperatures from -55 C to +125 C and is housed in a SOIC-J-20 package.

Feature Summary

• Octal 3-state non-inverting buffer design for bus-oriented systems
• Dual active-low output enables for high impedance control
• CMOS technology providing high noise immunity and low power consumption

Applications

• Memory address drivers
• Clock drivers
• Bus-oriented systems

Procurement Notes

Verify component status as the MC74HC541AF is listed as obsolete or discontinued by the manufacturer. Confirm availability through authorized distributors or secondary markets. Ensure compatibility with existing PCB layouts due to the specific SOIC-J-20 package dimensions. Check for RoHS compliance details in official documentation before integration.

Selection Notes

Select this component for applications requiring octal buffering with 3-state capability in harsh environments. The wide operating temperature range supports industrial use. Verify that the 2V to 6V supply range matches system requirements. Consider pinout compatibility with LS541 equivalents if replacing legacy designs.

Part Context

This part belongs to the HC logic family, utilizing silicon gate CMOS technology. It serves as a high-speed buffer compatible with standard CMOS and LSTTL outputs. The device is designed for memory address and clock driving in digital systems.

Replacement Considerations

Check for direct substitutes like MM74HC541N or TC74HC541AF. Verify pinout and electrical specifications match. Consider obsolescence status when selecting alternatives.
