CD74HC541M

Overview

The CD74HC541M is an octal buffer and line driver manufactured by Texas Instruments, belonging to the HC logic family. It features eight non-inverting inputs and outputs with three-state capability. The device operates within a supply voltage range of 2 V to 6 V. Key electrical characteristics include a high-level output current of -7.8 mA and a low-level output current of 7.8 mA. Static current consumption is typically 8 µA, while operating power supply current reaches 80 µA. It functions reliably across a temperature range from -55 °C to +125 °C and is housed in a SOIC-20 package.

Feature Summary

• Octal configuration providing eight independent non-inverting signal paths
• Three-state outputs allowing effective bus line driving and isolation
• Wide operating voltage range supporting diverse system power requirements
• Extended industrial temperature rating for harsh environment operation

Applications

• Bus-oriented architectures requiring data buffering
• Memory address drivers for digital systems

• Signal routing between different voltage domains

Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and temperature grade. Ensure the ordering part number matches the required tape-and-reel or tube quantity if applicable. Confirm RoHS compliance status through the manufacturer's latest documentation before finalizing procurement specifications.

Selection Notes

Select this component when designing systems requiring high-speed octal buffering with wide voltage tolerance. Consider the HC series performance metrics relative to system speed requirements. Evaluate the SOIC-20 footprint constraints during PCB layout planning. Verify that the input logic levels are compatible with the source devices driving the buffer inputs.

Part Context

This component belongs to the SN74HC541 family of octal buffers and line drivers. It shares functional similarities with other members like the SN74HC541PWR but differs in packaging and specific manufacturing revisions. The HC series represents a high-speed CMOS technology offering improved switching speeds compared to legacy LS counterparts while maintaining low power consumption profiles suitable for modern digital applications.

Replacement Considerations

Direct substitutes include the SN74HC541N and SN74HC541PW. Verify pin compatibility and electrical parameters before substitution.
