MC74VHC541MEL

Overview

The MC74VHC541MEL is an octal buffer and line driver manufactured by onsemi, belonging to the VHC logic family. It features eight non-inverting inputs with three-state outputs, housed in a 20-pin SOEIAJ package. The device supports a supply voltage range of 2V to 5.5V and operates within a temperature range of -55°C to 125°C. It provides a maximum propagation delay of 12ns at CL=50pF and delivers output currents of 8mA for both high and low states.

Feature Summary

• Octal configuration providing eight independent non-inverting buffer channels
• Three-state output capability allowing bus-oriented connections
• High-speed CMOS technology ensuring fast switching performance
• Wide operating voltage range supporting 2V to 5.5V supply rails

Applications

• Memory module data buffering
• Clock distribution networks
• Bus-oriented architectures requiring signal isolation
• Industrial control systems operating in extreme temperatures

Procurement Notes

Verify the specific suffix 'MEL' against the official datasheet to confirm the SOEIAJ-20 package variant. Ensure the procurement source provides RoHS compliance documentation if required for your assembly process. Confirm that the operating temperature grade matches your system's thermal requirements, as this part supports extended industrial ranges. Cross-reference the manufacturer part number with authorized distributors to avoid obsolete or counterfeit inventory.

Selection Notes

Select this component when an octal buffer with three-state outputs is required for high-speed digital interfaces. The VHC series offers superior speed compared to standard HC logic while maintaining CMOS power efficiency. Consider the 2V to 5.5V supply range for compatibility with various logic families. The wide temperature range makes it suitable for harsh environments where standard commercial parts may fail.

Part Context

This component is part of onsemi's extensive 74VHC logic portfolio, designed for high-performance digital applications. The 74VHC541 serves as a foundational building block for data routing and signal conditioning in complex electronic systems. Its octal structure allows for efficient management of multiple data lines within a single integrated circuit footprint.

Replacement Considerations

Check for MC74VHC541MELG as a potential equivalent from the same manufacturer family. Verify pinout compatibility and electrical specifications before substituting with other octal buffers like the 74HC541 variants, noting differences in speed and voltage thresholds.
