MC74HC541ADWR2G-Q

Overview

The MC74HC541ADWR2G-Q is an octal 3-state noninverting buffer/line driver manufactured by onsemi. It utilizes high-performance silicon-gate CMOS technology and operates within a DC supply voltage range of 2.0 to 6.0 V. The device features inputs and outputs positioned on opposite sides of the package, facilitating efficient PCB layout for bus-oriented systems. It includes two ANDed active-low output enables (OE1, OE2) that control the high-impedance state. The component is AEC-Q100 qualified and PPAP capable, designed for automotive applications requiring unique site and control change requirements.

Feature Summary

• Octal 3-state noninverting buffer design with inputs and outputs on opposite package sides
• Two ANDed active-low output enables for precise bus control
• AEC-Q100 qualified and PPAP capable for automotive reliability standards
• Compatible with Standard CMOS outputs and LSTTL loads via external pull-up resistors

Applications

• 3-state memory address drivers
• Clock drivers in bus-oriented systems
• Automotive electronic modules requiring AEC-Q100 qualification

Procurement Notes

Verify the specific -Q suffix indicates AEC-Q100 qualification and PPAP capability as defined in the official datasheet. Confirm the SOIC-20 Wide package designation matches the required footprint. Ensure the ordering information aligns with the manufacturer's current Tape & Reel specifications for this variant.

Selection Notes

Select this component when an octal noninverting buffer with 3-state capability is required for bus architectures. The HC series offers a wide operating voltage range suitable for various logic families. Consider the -Q suffix specifically for automotive environments where strict quality and site control changes are mandated by industry standards.

Part Context

This part belongs to the MC74HC541A family of octal buffers. It shares pinout compatibility with LS541 devices but provides higher speed and lower power consumption typical of CMOS technology. The -Q suffix distinguishes it from standard commercial variants by enforcing automotive-grade manufacturing controls and qualification protocols.
