MC74HC541ADTG

Overview

The MC74HC541ADTG is an octal 3-state non-inverting buffer and line driver manufactured by onsemi. It operates within a supply voltage range of 2.0 V to 6.0 V. The device features low input current of 1 µA and high noise immunity characteristic of CMOS devices. It includes two ANDed active-low output enables (OE1 and OE2) for bus-oriented systems. Outputs directly interface with CMOS, NMOS, and TTL loads. The component is housed in a 20-pin TSSOP package and supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Octal 3-state non-inverting buffer design for bus-oriented applications
• Dual active-low output enable inputs for precise control
• Wide operating voltage range supporting 2.0 V to 6.0 V
• High noise immunity and low power consumption typical of CMOS technology

Applications

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

Procurement Notes

Verify the specific suffix 'DTG' against the manufacturer's official datasheet to confirm the exact package type and RoHS compliance status. Ensure the ordering information matches the required pin configuration and thermal characteristics for the target application environment.

Selection Notes

Select this component when an octal buffer with 3-state outputs is required for interfacing between different logic families. It is suitable for designs needing wide voltage tolerance and high noise immunity. Verify that the TSSOP-20 package fits the PCB layout constraints and that the dual enable inputs align with the system control logic.

Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices. It serves as a standard solution for driving multiple lines in digital circuits. The device is functionally similar to other octal buffers but offers specific interface capabilities with TTL and NMOS loads due to its CMOS input structure.

Replacement Considerations

Check for direct replacements such as MC74HC541AF or other variants within the 74HC541 family. Ensure any substitute maintains the same 20-pin TSSOP footprint and electrical specifications.
