MC74VHC541DTR2G

Overview

The MC74VHC541DTR2G is an octal buffer and line driver manufactured by onsemi, belonging to the VHC logic series. It features eight non-inverting inputs and three-state outputs housed in a 20-pin TSSOP package. The device operates within a supply voltage range of 2 V to 5.5 V. Key electrical specifications include a maximum low-level output current of 8 mA and a high-level output current of -8 mA. Static current is specified at 2 uA, with a maximum operating supply current of 40 uA. The component supports surface mount installation and functions reliably across an extended temperature range from -55°C to +125°C.

Feature Summary

• Provides octal buffering capabilities with non-inverting signal transmission for digital data lines.
• Features three-state outputs that allow connection to multiple buses without interference.
• Operates over a wide supply voltage range suitable for various CMOS logic families.
• Designed for surface mount applications with an extended industrial temperature rating.

Applications

• Bus-oriented memory and address drivers
• Clock drivers and buffer circuits
• Multiple bus transceivers
• Cable drivers

Procurement Notes

Verify the specific suffix 'DTR2G' against the manufacturer's latest documentation to confirm the tape and reel packaging configuration and RoHS compliance status. Ensure the ordering quantity aligns with the standard factory pack size to avoid partial reel handling issues. Cross-reference the datasheet revision date to confirm pinout compatibility with existing PCB footprints before finalizing procurement orders.

Selection Notes

Select this component when an octal buffer with three-state control is required for systems operating between 2 V and 5.5 V. The VHC series offers faster propagation speeds compared to standard HC logic while maintaining CMOS power consumption. Consider the -55°C to +125°C operating range if the application demands robust performance in extreme environmental conditions or high-temperature industrial settings.

Part Context

This part belongs to the MC74VHC541 family of octal buffers and line drivers. It shares functional similarities with other members like the MC74AC541 and MC74ACT541 but differs in speed and voltage characteristics. The VHC series represents a high-speed CMOS technology optimized for low power dissipation and fast switching times, making it suitable for modern portable and battery-operated electronic devices requiring efficient signal management.

Replacement Considerations

Direct substitutes include the MC74VHC541DTG for tube packaging variants. For alternative sourcing, consider the SN74LV541ATDWR from Texas Instruments or the 74AHCT541D from Nexperia, ensuring voltage levels and package dimensions match the original design requirements.
