74LCX241MSAX

Overview

The Fairchild Semiconductor 74LCX241MSAX is an octal buffer and line driver featuring non-inverting logic with three-state outputs. It operates within a voltage range of 2.0V to 3.6V and utilizes a 20-pin SSOP package. The device incorporates 5V tolerant inputs and outputs, allowing safe interfacing between low-voltage components and 5V systems. Designed for high-speed applications, it provides significant drive capability while maintaining low power consumption typical of CMOS technology.

Feature Summary

• Provides eight non-inverting buffer channels with independent output enable control
• Features 5V tolerant I/O structure for mixed-voltage system compatibility
• Delivers high-speed performance suitable for memory address and clock driving

Applications

• Memory address drivers in computer systems
• Clock distribution networks
• Bus-oriented transmitters and receivers

Procurement Notes

Verify the specific suffix 'MSAX' against the manufacturer's current datasheet to confirm the tape-and-reel packaging configuration. Ensure the component meets RoHS compliance requirements if applicable to your assembly process. Cross-reference the pinout diagram with your PCB layout to confirm alignment with the 20-lead SSOP footprint before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring bidirectional data flow or simple buffering between 3.3V logic domains and 5V peripherals. It serves as a direct replacement for older HC series buffers where lower supply voltage operation is required. Consider its propagation delay specifications relative to your system clock speed to ensure signal integrity is maintained across the bus lines.

Part Context

This part belongs to the LCX family of low-voltage CMOS logic devices manufactured by Fairchild Semiconductor. The LCX series is engineered to bridge the gap between legacy 5V TTL/CMOS standards and modern low-voltage digital circuits. It shares functional similarities with other octal buffers like the 74HC241 but offers improved power efficiency and voltage tolerance characteristics.

Replacement Considerations

The MM74HC541MTCX is a documented alternative from the same manufacturer offering similar octal buffer functionality. Verify that the HC series operating voltage range aligns with your specific design constraints before substituting.
