MC74HC541AFELG

Overview

The MC74HC541AFELG is an octal 3-state non-inverting buffer, line driver, and line receiver manufactured by onsemi. It operates within a supply voltage range of 2.0 V to 6.0 V. The device features inputs and outputs positioned on opposite sides of the package to facilitate printed circuit board layout. It includes two ANDed active-low output enables for bus-oriented systems. The logic series is HC CMOS, and it is housed in a 20-lead SOIC-J package.

Feature Summary

• Octal 3-state non-inverting buffer design
• Inputs and outputs located on opposite package sides
• Two ANDed active-low output enables
• Compatible with Standard CMOS and LSTTL outputs

Applications

• 3-state memory address drivers
• Clock drivers
• Bus-oriented systems

Procurement Notes

Verify the specific suffix ELG against official datasheets to confirm package dimensions and tape-and-reel specifications. Confirm RoHS compliance status as manufacturing processes evolve. Check current lifecycle status as components may be subject to discontinuation or obsolescence notices from the manufacturer.

Selection Notes

Select this component when an octal buffer with high noise immunity and low input current is required. Ensure the system voltage falls within the 2.0 V to 6.0 V operating range. Verify that the 20-lead SOIC-J package fits the available PCB footprint and that the opposite-side I/O arrangement aligns with the routing strategy.

Part Context

This part belongs to the 74HC family of high-speed CMOS logic devices. It serves as a non-inverting counterpart to the 74HC540. The device is functionally identical in pinout to the LS541, allowing for potential compatibility in legacy designs requiring similar drive capabilities.

Replacement Considerations

Direct replacements include the MC74HC541ADWRG and MC74HC541DTG from onsemi. Cross-manufacturer equivalents such as the SN74HC541N from Texas Instruments or the CD74HC541M from ON Semiconductor (historical) may be considered if pinouts and electrical characteristics match.
