MC74HC541AFG

Overview

The MC74HC541AFG is an octal 3-state non-inverting buffer and line driver manufactured by onsemi. It utilizes advanced silicon gate CMOS technology to provide high-speed operation with low power consumption. The device features inputs and outputs on opposite sides of the package, facilitating printed circuit board layout. It includes two ANDed active-low output enables for bus-oriented systems. The logic series is HC, operating within a voltage range of 2.0 V to 6.0 V. It offers high noise immunity and is compatible with Standard CMOS outputs.

Feature Summary

• Octal 3-state non-inverting buffer design for bus-oriented applications
• Inputs and outputs located on opposite package sides for simplified PCB layout
• Two ANDed active-low output enable controls for precise signal gating
• High noise immunity characteristics inherent to CMOS technology

Applications

• 3-state memory address drivers
• Clock drivers in digital systems
• Bus-oriented system interconnects

Procurement Notes

Verify the specific suffix 'FG' against official onsemi documentation to confirm package type and tape/reel specifications. Ensure compatibility with existing footprint designs, as package dimensions vary. Confirm current availability status directly with authorized distributors, as lifecycle stages may affect procurement options.

Selection Notes

Select this component when an octal buffer with 3-state capability is required for high-speed CMOS interfaces. It serves as a pin-compatible alternative to LS541 devices. Consider the 2V to 6V operating range for flexibility in various supply voltages. Ensure input pull-up resistors are used if interfacing with LSTTL outputs for proper logic level translation.

Part Context

This part belongs to the 74HC541 family of octal buffers. It is functionally similar to the MM74HC541 but distinguished by its specific packaging configuration indicated by the suffix. The device is designed to replace older transistor-transistor logic (TTL) buffers while maintaining compatibility with standard CMOS logic families.

Replacement Considerations

The MC74HC541A is identified as having an identical pinout to the LS541. Other manufacturers produce equivalent parts such as the SN74HC541 from Texas Instruments or the HCT541 variants for TTL-compatible inputs.
