Procurement Notes

Verify the manufacturer marking on the component body matches Fairchild or ON Semiconductor branding, as Fairchild was acquired by ON Semiconductor. Confirm the package type is SOIC-20 and check for lead-free compliance markings. Ensure the part number suffix corresponds to the specific tape-and-reel or tube packaging variant required for your assembly process.

Selection Notes

Select this component when a low-voltage, high-speed octal flip-flop with three-state outputs is required. It is suitable for systems operating at reduced voltage levels compared to standard AC/ACT series devices. Consider the LVQ series for improved noise immunity and lower power consumption in battery-operated or energy-efficient designs requiring bus isolation capabilities.

Part Context

The 74LVQ374SC belongs to the LVQ family of low-voltage logic devices from Fairchild Semiconductor. This family is designed for applications requiring operation below standard 5V levels while maintaining compatibility with existing logic interfaces. The SCX suffix typically indicates a lead-free, tape-and-reel packaged version of the standard SOIC-20 device.

Replacement Considerations

The 74LVQ374SC can be replaced by other octal D-type flip-flops with three-state outputs from compatible low-voltage families. Verify pinout compatibility and voltage range specifications before substitution. Equivalent parts may include variants from other manufacturers offering similar low-voltage, high-speed performance characteristics.
