74LVC125ABQ-Q100X

Overview

The Nexperia 74LVC125ABQ-Q100X is a quad non-inverting buffer and line driver with three-state outputs, qualified to AEC-Q100 Grade 1 for automotive use. It operates within a supply voltage range of 2.3 V to 3.6 V, featuring 5 V tolerant inputs and outputs that interface directly with 5 V logic devices. The device provides low power consumption and includes ESD protection exceeding 2 kV (HBM) and 1 kV (CDM). Packaged in DHVQFN14 (SOT762-1), it supports an ambient temperature range from -40 °C to +125 °C.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• Five-volt tolerant inputs and outputs for mixed-voltage system interfacing
• Three-state outputs controlled by active-low enable inputs
• DHVQFN package with side-wettable flanks enabling automatic optical inspection

Applications

• Automotive electronic systems requiring robust signal buffering
• Mixed 3.3 V and 5 V logic level translation environments
• High-noise immunity applications utilizing direct TTL level interfaces

Procurement Notes

Verify the specific suffix 'X' against official Nexperia documentation to confirm reel packaging specifications. Ensure the DHVQFN14 package variant matches the required thermal and mechanical constraints. Confirm AEC-Q100 Grade 1 qualification status aligns with target automotive reliability requirements before finalizing procurement orders.

Selection Notes

Select this component when four independent buffered channels with high-impedance states are required. The wide operating temperature range and automotive qualification make it suitable for harsh environments. Verify that the 2.3 V to 3.6 V supply voltage range meets the system's power rail specifications and that 5 V tolerance is necessary for input/output compatibility.

Part Context

This part belongs to the Nexperia 74LVC125A-Q100 family of quad buffers. It shares functional characteristics with other members of the series but differs in package type. The ABQ designation specifically identifies the DHVQFN14 package option, distinguishing it from SO14 or TSSOP14 variants within the same logical family.

Replacement Considerations

Direct substitutes include other 74LVC125A-Q100 variants such as 74LVC125AD-Q100 or 74LVC125APW-Q100, provided the package footprint and pinout compatibility are verified. Cross-referencing with equivalent automotive-grade quad buffers from other manufacturers requires careful evaluation of electrical parameters and physical dimensions.
