MC74HC541ADTR2G-Q

Overview

The MC74HC541ADTR2G-Q is an octal 3-state non-inverting buffer and line driver from the 74HC series. It operates within a supply voltage range of 2.0 V to 6.0 V. The device features inputs and outputs on opposite sides of the package, facilitating easier printed circuit board layout for bus-oriented systems. It includes two ANDed active-low output enables. The component is designed for high noise immunity and low input current characteristics typical of CMOS devices.

Feature Summary

• Octal 3-state non-inverting buffer and line driver configuration
• Inputs and outputs located on opposite package sides for simplified routing
• Two ANDed active-low output enable controls
• High noise immunity with low input current consumption

Applications

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

Procurement Notes

Verify the -Q suffix indicates automotive qualification status against official datasheets. Confirm RoHS compliance and material declarations. Ensure the TSSOP-20 package dimensions match design constraints. Validate operating temperature ranges for specific environmental conditions.

Selection Notes

Select this component for applications requiring octal buffering with bidirectional capability on buses. Compare propagation delay specifications against system timing requirements. Evaluate power consumption at the target operating voltage. Consider the opposite-side I/O layout benefits for PCB density.

Part Context

This part belongs to the 74HC family of high-speed CMOS logic devices. It shares pinout compatibility with older LS541 designs while offering improved CMOS performance. The device serves as a standard solution for interfacing between different logic families or driving high-capacitance loads in digital circuits.

Replacement Considerations

Check for direct pin-compatible alternatives such as MC74HC541ADWR2G or MC74HC541DTR2G. Verify if the -Q automotive grade requirement can be met by standard commercial variants if qualification is not mandatory.
