MC74HC541ADTR2

Overview

The MC74HC541ADTR2 is an octal 3-state non-inverting buffer and line driver manufactured by onsemi. It operates within a supply voltage range of 2.0V to 6.0V, ensuring compatibility with standard CMOS outputs and LSTTL outputs when external pull-up resistors are utilized. The device features inputs and outputs positioned on opposite sides of the package to facilitate efficient printed circuit board layout. It includes two ANDed active-low output enables for precise bus control. Designed for memory address drivers, clock drivers, and other bus-oriented systems, it offers low input current and high noise immunity characteristic of CMOS devices.

Feature Summary

• Octal 3-state non-inverting buffer design
• Opposite-side input/output pin configuration
• Dual ANDed active-low output enables
• High noise immunity and low input current

Applications

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

Procurement Notes

Verify the specific suffix 'DTR2' against the official datasheet to confirm tape-and-reel packaging and RoHS compliance status. Ensure the operating environment remains within the specified 2.0V to 6.0V supply range. Confirm that external pull-up resistors are included in the design if interfacing with LSTTL outputs is required. Check for any recent product change notices regarding manufacturing location or material declarations.

Selection Notes

Select this component when an octal buffer with 3-state capability is needed for bus applications. It is suitable for designs requiring interface between CMOS and TTL logic families. Consider the 2.0V to 6.0V operating range for flexibility in power supply design. The opposite-side pinout aids in routing dense PCB layouts compared to same-side configurations.

Part Context

This part belongs to the 74HC541 family of octal buffers. It shares functional similarities with the MC74HC540A but provides non-inverting outputs instead. The device is designed to drive up to 15 LSTTL loads directly. It complies with JEDEC Standard No. 7A requirements for CMOS device characteristics.

Replacement Considerations

Direct replacements include the MC74HC541ADR2G from onsemi. Other compatible parts from different manufacturers may include the SN74HC541N from Texas Instruments or the CD74HC541M from Harris Semiconductor, provided pinouts and electrical specifications match.
