74LVC125AD-Q100J

Overview

The Nexperia 74LVC125AD-Q100J is a quad non-inverting buffer and line driver featuring three-state outputs controlled by active-low output enable inputs. It operates within a supply voltage range of 2.3 V to 3.6 V and supports 5 V tolerant inputs and outputs, allowing direct interfacing with 5 V logic devices. The component is qualified to AEC-Q100 Grade 1 standards for automotive applications and functions reliably across an ambient temperature range of -40 °C to +125 °C.

Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1 standard
• 5 V tolerant inputs and outputs for mixed-voltage system interfacing
• Three-state outputs controlled by active-low enable signals
• Wide operating temperature range suitable for harsh environments

Applications

• Automotive electronic systems requiring robust signal buffering
• Mixed-voltage logic interfaces between 3.3 V and 5 V domains
• High-reliability data transmission lines in vehicle control units

Procurement Notes

Verify the specific package variant against design requirements, as the AD suffix denotes the SO14 (SOT108-1) plastic small outline package. Confirm that the AEC-Q100 Grade 1 qualification aligns with target automotive reliability standards. Ensure input and output voltage levels remain within the specified 5 V tolerance limits during operation.

Selection Notes

Select this component when designing circuits that require four independent non-inverting buffers with high-impedance states. It is appropriate for applications needing direct compatibility with 5 V logic signals while powered by lower voltages. Consider the SO14 package dimensions if surface-mount space constraints are defined by the SOT108-1 footprint.

Part Context

This device belongs to the Nexperia 74LVC125A-Q100 family of automotive-grade logic ICs. The family includes alternative packaging options such as TSSOP14 and DHVQFN14 variants, all sharing identical electrical characteristics and functional specifications. The product line is designed to meet stringent automotive quality and reliability requirements.

Replacement Considerations

Direct substitutes include other 74LVC125A-Q100 variants with different packages, such as the APW (TSSOP14) or ABQ (DHVQFN14) suffixes. Cross-brand replacements must match the quad buffer functionality, 3-state capability, and 5 V tolerance specifications.
