MC74HC541AFEL

Overview

The MC74HC541AFEL is an octal 3-state non-inverting buffer and line driver manufactured by onsemi. It operates within a supply voltage range of 2.0 V to 6.0 V. The device features inputs and outputs located on opposite sides of the package, facilitating printed circuit board layout. It includes two ANDed active-low output enables. The component is housed in a 20-lead SOIC-J package.

Feature Summary

• Octal 3-state non-inverting buffer design
• Opposite-side input/output pinout for simplified PCB routing
• Dual active-low output enable control

Applications

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

Procurement Notes

Verify the specific suffix 'FEL' against official datasheets, as standard listings often use 'AF'. Confirm current availability status, as older HC series variants may be discontinued or subject to limited supply constraints. Ensure the package type matches the required footprint.

Selection Notes

Select this component for applications requiring high noise immunity and low static power consumption typical of CMOS technology. It serves as a direct replacement for LS541 pinouts while offering broader voltage compatibility. Verify that the 2.0 V minimum operating voltage meets system requirements.

Part Context

This part belongs to the 74HC logic family, designed for high-speed operation with CMOS compatibility. It functions similarly to the inverting MC74HC540A but provides non-inverting signal paths. The device is intended for driving bus loads and interfacing with various logic families.
