74LVC138APW/AUJ Equivalent & Substitute Parts

Part Overview

The 74LVC138APW/AUJ is a logic decoder/demultiplexer IC manufactured by NXP USA Inc., designed for 1 x 3:8 decoding applications in 16-TSSOP surface mount packaging. This active product operates across a single supply voltage range of 1.2V to 3.6V with output currents of 24mA (high and low), making it suitable for low-voltage digital logic applications. The part is ROHS3 compliant and carries MSL Level 1 (unlimited moisture sensitivity rating).

Equivalent substitute parts are necessary when the primary part is unavailable, when alternative packaging formats are required for manufacturing processes, or when automotive-grade qualification is needed for specific applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74LVC138APW/AUJ is determined by strict equivalence across the following parameters:

• Functional Type: Decoder/Demultiplexer with 1 x 3:8 circuit configuration
• Electrical Performance: Output current capability of 24mA (high and low), single supply voltage operation from 1.2V to 3.6V
• Temperature Range: Operating specification of -40°C to +125°C
• Package Compatibility: 16-TSSOP surface mount package with 0.173" width (4.40mm)
• Compliance Standards: ROHS3 compliance and MSL Level 1 rating

The identified substitute parts maintain full parametric equivalence across all electrical and mechanical specifications. Packaging format variations (Cut Tape & Digi-Reel vs. Tape & Reel) and automotive qualification (AEC-Q100) represent secondary differentiators that do not affect functional interchangeability.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain identical electrical and mechanical specifications, ensuring direct functional interchangeability in 74LVC138 decoder/demultiplexer applications. Selection between these active products should be based on:

Packaging and Supply Chain Requirements: The 74LVC138APW,118 (Nexperia) is available in Cut Tape & Digi-Reel format with higher inventory (13,011 pcs), suitable for mixed-volume manufacturing environments. The 74LVC138APW-Q100J (Nexperia) is supplied in Tape & Reel format with AEC-Q100 automotive qualification, appropriate for automotive-grade applications requiring formal qualification documentation.

Compliance and Regulatory Status: All parts carry ROHS3 compliance and REACH unaffected status, meeting standard industrial and commercial regulatory requirements. The 74LVC138APW-Q100J additionally carries AEC-Q100 qualification for automotive applications.

Inventory and Availability: The 74LVC138APW,118 offers the highest stock availability (13,011 pcs), followed by 74LVC138APW-Q100J (2,576 pcs), supporting different procurement timelines and volume requirements.

Frequently Asked Questions (FAQ)

Q: Are these parts pin-compatible? A: Yes. All three parts use the 16-TSSOP package with identical pinout and functional configuration (1 x 3:8 decoder/demultiplexer), ensuring direct PCB compatibility without layout modifications.

Q: What is the difference between Cut Tape & Digi-Reel and Tape & Reel packaging? A: Cut Tape & Digi-Reel format is suitable for mixed-volume production and manual component handling. Tape & Reel format is optimized for high-volume automated assembly processes. Both formats contain the same die and electrical performance.

Q: Can I use the automotive-grade 74LVC138APW-Q100J in non-automotive applications? A: Yes. The AEC-Q100 qualification is an additional certification that does not restrict use in standard industrial or commercial applications. The part meets all standard specifications and can be used as a direct substitute in any 74LVC138 application.

Q: Are there any electrical performance differences between NXP and Nexperia versions? A: No. Both manufacturers produce parts with identical electrical specifications: 24mA output current, 1.2V–3.6V supply voltage range, and -40°C to +125°C operating temperature. Functional performance is equivalent.

Q: What does MSL Level 1 (Unlimited) mean for storage and handling? A: MSL Level 1 indicates unlimited shelf life without moisture baking requirements. These parts do not require special moisture control during storage or handling, simplifying inventory management and reducing preparation time before assembly.
