74LVC86AT14-13 Equivalent & Substitute Parts

Part Overview

The 74LVC86AT14-13 is a 4-channel, 2-input XOR (Exclusive OR) logic gate integrated circuit manufactured by Diodes Incorporated. This device operates across a wide supply voltage range of 1.65V to 5.5V and is housed in a 14-TSSOP surface mount package. The part maintains Active product status and is RoHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent logic functionality, package form factor, and electrical operating parameters align within specified tolerances. Alternative sources become necessary due to inventory availability, supply chain considerations, or design flexibility requirements while maintaining functional equivalence.

Substitute Part Grouping Explanation

Substitution eligibility for the 74LVC86AT14-13 is determined by the following criteria:

Functional Equivalence: All substitute parts must implement 4-channel, 2-input XOR logic with identical truth table behavior.

Package Compatibility: All parts must use the 14-TSSOP surface mount package with identical pin configuration and mechanical dimensions (0.173", 4.40mm width).

Electrical Operating Range: Substitute parts must support the operating temperature range of -40°C to 125°C and maintain output current specifications of 24mA for both high and low states.

Compliance Standards: All parts must maintain RoHS3 compliance and MSL 1 rating to ensure compatibility with standard manufacturing and storage processes.

Supply Voltage Overlap: While individual supply voltage ranges may differ, substitute parts must operate within the application's required voltage window.

The following parts meet these substitution criteria:

• 74LVC86APW,118 (Nexperia USA Inc.)
• SN74LVC86APWR (Texas Instruments)

Parameter Comparison

Engineering Selection Recommendations

74LVC86APW,118 (Nexperia USA Inc.): This substitute part provides full functional equivalence with identical package and pin configuration. The supply voltage range is narrower (1.2V to 3.6V) compared to the primary part, requiring verification that the application operates within this window. Quiescent current is higher at 40 µA versus 10 µA for the primary part. Propagation delay is slightly increased to 5ns at 3.3V and 50pF load. All compliance certifications (RoHS3, MSL 1) are maintained. This part is suitable for applications where the reduced supply voltage range is acceptable.

SN74LVC86APWR (Texas Instruments): This substitute part offers the closest electrical performance match to the primary part, with identical propagation delay of 4.4ns at 3.3V and 50pF load. Quiescent current is significantly lower at 1 µA. The supply voltage range (1.65V to 3.6V) overlaps with the primary part's lower operating window. Input logic level thresholds are more restrictive than the primary part. All compliance certifications (RoHS3, MSL 1) are maintained. This part is suitable for applications requiring low quiescent current and operating within the specified voltage range.

Both substitute parts maintain Active product status and full regulatory compliance, ensuring long-term availability and manufacturing process compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 74LVC86APW,118 be used as a direct replacement for the 74LVC86AT14-13?

A: The 74LVC86APW,118 provides functional equivalence in logic operation, package form factor, and pin configuration. However, the supply voltage range is restricted to 1.2V to 3.6V. Direct substitution is valid only if the application operates within this voltage window. The higher quiescent current (40 µA versus 10 µA) may impact power consumption in battery-powered applications.

Q: What are the key differences between the SN74LVC86APWR and the primary 74LVC86AT14-13?

A: The SN74LVC86APWR matches the primary part's propagation delay performance (4.4ns) and offers superior quiescent current characteristics (1 µA). The supply voltage range is 1.65V to 3.6V, which is narrower than the primary part's 1.65V to 5.5V range. Input logic level thresholds are more tightly specified. Both parts share identical package specifications and compliance certifications.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the 14-TSSOP package with identical pin assignments for the 4-channel, 2-input XOR logic function. Physical dimensions are identical (0.173", 4.40mm width), allowing direct PCB footprint compatibility.

Q: Which substitute part should be selected for low-power applications?

A: The SN74LVC86APWR is the optimal choice for low-power applications, with quiescent current of only 1 µA compared to 10 µA for the primary part and 40 µA for the Nexperia alternative.

Q: Do all parts meet the same compliance requirements?

A: Yes. All three parts are RoHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating. All parts are classified under ECCN EAR99 and HTSUS 8542.39.0001.

Q: What is the impact of propagation delay differences on circuit performance?

A: The primary part and SN74LVC86APWR both specify 4.4ns maximum propagation delay at 3.3V with 50pF load. The 74LVC86APW,118 specifies 5ns under identical conditions, representing a 0.6ns increase. This difference is negligible for most digital logic applications but may be significant in high-speed timing-critical circuits.

Q: Can these parts be mixed within the same design?

A: While all parts are functionally equivalent and pin-compatible, mixing different manufacturers within a single design is not recommended due to potential variations in quiescent current, propagation delay, and input logic level thresholds. Consistent sourcing from a single manufacturer is preferred for design consistency and manufacturing traceability.
