MC74HC541ADT

Overview

The MC74HC541ADT is an octal 3-state non-inverting buffer, line driver, and line receiver manufactured by onsemi. It belongs to the HC logic family and 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 applications. The component is designed to drive up to 15 LSTTL loads and interfaces directly with CMOS, NMOS, and TTL circuits.

Feature Summary

• Octal configuration with non-inverting signal path
• Dual active-low output enable control
• Opposite-side input/output pin arrangement
• Direct interface capability with CMOS, NMOS, and TTL

Applications

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

Procurement Notes

Verify the specific suffix 'DT' against the manufacturer's current datasheet to confirm the exact package type and tape-and-reel specifications. Ensure the ordering part number matches the required RoHS compliance status and moisture sensitivity level defined in the latest production data. Cross-reference the date code to confirm availability and manufacturing origin.

Selection Notes

Select this component when an octal buffer with high noise immunity and wide voltage operation is required. The HC series offers low static power consumption suitable for general-purpose digital logic. Consider the physical pinout compatibility with LS541 equivalents if replacing legacy designs. Verify that the 2V to 6V operating range aligns with the system power supply constraints.

Part Context

This device is part of the standard 74HC logic family, providing high-speed CMOS performance. It serves as a non-inverting counterpart to the 74HC540A. The design supports complex digital systems requiring multiple buffered signals with independent tri-state control capabilities for efficient bus management.

Replacement Considerations

Check for direct replacements such as SN74HC541 or MM74HC541. Verify pinout compatibility and electrical characteristics before substitution.
