74LVC125ABQ,115

Overview

The Nexperia 74LVC125ABQ,115 is a quad buffer and line driver featuring 3-state outputs controlled by active-low output enable inputs (nOE). It operates within a supply voltage range of 1.2 V to 3.6 V and supports overvoltage tolerant inputs up to 5.5 V. The device utilizes DHVQFN14 packaging (SOT762-1) with dimensions of 2.5 x 3 x 0.85 mm. It provides an output drive capability of ±24 mA at 3.0 V and includes IOFF circuitry for partial power-down applications. Operating temperatures span from -40 °C to +125 °C.

Feature Summary

• Provides four non-inverting buffers with independent 3-state control via active-low nOE inputs.
• Features Schmitt-trigger action on all inputs to ensure tolerance for slow rise and fall times.
• Includes IOFF circuitry that disables outputs to prevent damaging backflow currents during partial power-down states.
• Supports direct interfacing with TTL levels and mixed 3.3 V/5 V environments through 5.5 V tolerant inputs.

Applications

• Translating signals between mixed 3.3 V and 5 V logic environments
• Clock distribution and buffering in high-speed digital systems
• Partial power-down mode operation for low-power standby states

Selection Notes

Select this component when a quad buffer with 3-state control is required for mixed-voltage signal translation. The DHVQFN14 package suits space-constrained designs needing thermal enhancement. Ensure input transition rates comply with JEDEC standards for the chosen supply voltage. This part is suitable for general-purpose logic buffering but lacks automotive qualification compared to the -Q100 variants.

Part Context

This device belongs to the 74LVC125A family of quad buffers with 3-state outputs. The ABQ suffix specifically denotes the DHVQFN14 leadless package variant. It shares functional characteristics with other LVC series drivers but differs in physical footprint and thermal properties. The product data sheet confirms its status as a production-grade component compliant with standard JEDEC logic specifications.

Replacement Considerations

The 74LVC125AD-Q100J serves as a pin-compatible alternative in SO14 packaging with automotive qualification. For identical DHVQFN14 footprints, verify availability of other LVC125 variants from the same manufacturer family.
