74LVQ241QSC

Overview

The Fairchild Semiconductor 74LVQ241QSC is a low-voltage octal buffer and line driver featuring three-state outputs. It operates within a supply voltage range of 1.65V to 3.6V, ensuring compatibility with modern low-power digital systems. The device provides eight non-inverting buffers or line drivers in a single package, designed to improve performance and printed circuit board density. It supports direct driving of bus lines and terminated transmission lines, offering high fanout capabilities and improved noise rejection through input hysteresis.

Feature Summary

• Low-voltage operation compatible with 1.65V to 3.6V power supplies
• Octal configuration providing eight independent non-inverting buffers
• Three-state outputs allow direct connection to bus-oriented structures
• Enhanced noise immunity via input hysteresis characteristics

Applications

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

Procurement Notes

Verify the specific suffix 'QSC' against the manufacturer's current datasheet to confirm package type and RoHS compliance status. Ensure the component matches the required operating temperature range for your application. Cross-reference the ordering information with official Fairchild or ON Semiconductor documentation to avoid counterfeit parts. Confirm pin-out compatibility if replacing existing designs.

Selection Notes

Select this component when designing systems requiring low-voltage logic interfacing with high-speed data buses. The octal configuration reduces component count compared to using multiple single-channel buffers. Consider the three-state capability for shared bus architectures where multiple devices must drive common lines without contention. Evaluate propagation delay specifications against system timing requirements.

Part Context

This part belongs to the 74LVQ series of low-voltage CMOS logic devices. It serves as a functional equivalent to standard 74LS241 buffers but optimized for lower voltage operation. The QSC suffix typically denotes a specific surface-mount package variant, such as a small-outline package, distinguishing it from through-hole or other package options within the same logical family.

Replacement Considerations

Check for 74LVQ241 variants with different package suffixes if pin compatibility is required. Verify that substitute components maintain the same 1.65V-3.6V operating range. Ensure replacement parts offer comparable propagation delays and output drive strengths for signal integrity.
