74LCX541BQX

Overview

The MC74LCX541BQX is an octal buffer and line driver from the LCX logic family, manufactured by onsemi. It operates within a supply voltage range of 2 V to 3.6 V and features non-inverting outputs with three-state capability. The device utilizes a 20-DQFN package (2.5x4.5 mm) and provides high-level output current of -24 mA and low-level output current of 24 mA. Static current is specified at 10 uA. The component is classified as obsolete or discontinued in major distribution channels.

Feature Summary

• Three-state outputs allow isolation from the bus when not selected
• Flow-through pinout architecture facilitates printed circuit board layout
• Compatible with 2.5 V and 3.3 V power domains

Applications

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

Procurement Notes

Verify availability status carefully as this part number is listed as obsolete or discontinued by major distributors. Confirm if replacement variants such as the MC74LCX541DWR2G are suitable for your specific design requirements. Check datasheet revisions for any functional changes before finalizing procurement plans.

Selection Notes

Select this component for low-voltage applications requiring octal buffering between 2 V and 3.6 V supplies. Ensure the 20-DQFN package fits your PCB constraints. Compare against the MC74LCX541DWR2G if tape-and-reel packaging is preferred over the DQFN form factor.

Part Context

This device belongs to the LCX series of advanced high-speed CMOS logic. It shares functional similarities with the AC/ACT families but is optimized for lower voltage operation. The octal configuration provides eight independent buffers, making it suitable for parallel data paths in microprocessor systems.

Replacement Considerations

The MC74LCX541DWR2G is a documented alternative offering similar electrical characteristics in an SOIC-20 package. Verify pin compatibility and package dimensions before substitution.
