74LVQ125SC

Overview

The onsemi 74LVQ125SC is a low voltage quad buffer with 3-STATE outputs, designed for low power and low noise applications. It operates within a supply voltage range of 2.0V to 3.6V and supports an operating temperature from -40°C to +85°C. The device features four independent non-inverting buffers in a 14-Lead Small Outline Integrated Circuit (SOIC) package. Key electrical characteristics include a maximum propagation delay of 14.0 ns at 2.7V and 10.0 ns at 3.3V, with guaranteed simultaneous switching noise levels and dynamic threshold performance.

Feature Summary

• Contains four independent non-inverting buffers with 3-STATE outputs
• Ideal for low power and low noise 3.3V applications
• Guarantees simultaneous switching noise level and dynamic threshold performance
• Ensures pin-to-pin skew AC performance

Applications

• Low power/low noise 3.3V applications
• Transmission lines with impedances as low as 75 Ω
• General purpose buffering in digital circuits

Procurement Notes

Verify the component status before procurement, as the 74LVQ125SC may be obsolete or discontinued depending on current inventory data. Confirm the package type matches the required 14-Lead SOIC specification. Ensure that any ordering suffixes are correctly interpreted if alternative packaging options like tape and reel are needed. Cross-reference the manufacturer part number with official distributor databases to confirm availability and lead times.

Selection Notes

Select the 74LVQ125SC when low voltage operation between 2.0V and 3.6V is required. Consider this component for designs needing guaranteed simultaneous switching noise performance and dynamic threshold capabilities. The 14-SOIC package is suitable for surface mount applications requiring a narrow footprint. Verify that the input voltage levels align with the specified VIH and VIL thresholds for reliable operation.

Part Context

The 74LVQ125SC belongs to the LVQ series of logic integrated circuits manufactured by onsemi (formerly Fairchild Semiconductor). This series focuses on low voltage applications, providing robust performance in 3.3V systems. The device is categorized as a buffer and line driver, offering high drive capability and low output impedance. It is part of a broader family of logic ICs designed for various digital signal processing needs.

Replacement Considerations

Check for available substitutes such as MC74LVX125DG or SN74LV125AD if the 74LVQ125SC is unavailable. Ensure that replacement parts maintain compatibility with the 2.0V to 3.6V supply voltage range and the 14-SOIC package form factor. Verify that the alternative components meet the same electrical specifications for propagation delay and output drive current.
