SN74LVC2G86DCUTE4 Equivalent & Substitute Parts

Part Overview

The SN74LVC2G86DCUTE4 is a 2-channel XOR (Exclusive OR) logic IC manufactured by Texas Instruments in 8-VSSOP packaging. This part operates across a wide voltage supply range of 1.65V to 5.5V with low quiescent current and is suitable for general-purpose digital logic applications. The product status is listed as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SN74LVC2G86DCUTE4 is determined by the following critical parameters:

• Logic Function: All substitutes must implement 2-channel, 2-input XOR logic
• Voltage Supply Range: All substitutes must support 1.65V ~ 5.5V operation
• Output Current Capability: All substitutes must provide 32mA output current (high and low)
• Propagation Delay: Maximum 3.6ns @ 5V, 50pF or faster
• Operating Temperature Range: Minimum -40°C ~ 125°C
• Mounting Type: Surface mount only
• Package Compatibility: 8-pin packages with equivalent pinout and mechanical dimensions

Substitutes are grouped into two categories: parametric equivalents from Texas Instruments with identical electrical specifications, and manufacturer-recommended alternatives from Nexperia and onsemi that meet or exceed the core electrical requirements while offering different packaging or performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Direct Parametric Equivalents (Recommended Primary Substitutes)

SN74LVC2G86DCUR and SN74LVC2G86DCUT are direct parametric equivalents manufactured by Texas Instruments with identical electrical specifications to the obsolete SN74LVC2G86DCUTE4. Both parts maintain the same 10 µA quiescent current, 3.6ns propagation delay, and 8-VFSOP package. These parts are in active production status with substantial inventory availability.

Nexperia Alternatives

74LVC2G86DC,125 and 74LVC2G86DP,125 are active Nexperia products that meet all core electrical requirements. The 74LVC2G86DC,125 maintains the 8-VFSOP package with improved quiescent current of 4 µA. The 74LVC2G86DP,125 uses an 8-TSSOP package with the same 4 µA quiescent current. Both are ROHS3 compliant. The 74LVC2G86DC-Q100H variant includes AEC-Q100 automotive qualification for applications requiring automotive-grade components.

onsemi Alternatives

NC7WZ86K8X and NL27WZ86USG from onsemi provide the lowest quiescent current at 1 µA with slightly higher propagation delay of 4.2ns. The NL27WZ86USG maintains the full -40°C ~ 125°C operating temperature range, while NC7WZ86K8X operates to -40°C ~ 85°C. Both are ROHS3 compliant and in active production.

All substitute parts are ROHS3 compliant and REACH unaffected, meeting standard environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can I directly replace SN74LVC2G86DCUTE4 with SN74LVC2G86DCUR or SN74LVC2G86DCUT?

A: Yes. Both SN74LVC2G86DCUR and SN74LVC2G86DCUT are parametric equivalents with identical electrical specifications and 8-VFSOP packaging. The primary difference is packaging format (Cut Tape vs. Digi-Reel). Both are pin-compatible and functionally equivalent.

Q: What is the difference between 8-VFSOP and 8-TSSOP packages?

A: Both are 8-pin surface mount packages with equivalent pinout for this XOR logic function. The 8-VFSOP has a width of 0.091" (2.30mm), while 8-TSSOP has a width of 0.118" (3.00mm). Package selection depends on PCB layout constraints and assembly equipment capabilities.

Q: Are onsemi parts (NC7WZ86K8X, NL27WZ86USG) suitable replacements?

A: Yes, both onsemi parts meet the core electrical requirements with superior quiescent current performance (1 µA vs. 10 µA). The propagation delay is slightly higher at 4.2ns versus 3.6ns, which remains acceptable for most general-purpose logic applications. NC7WZ86K8X operates to 85°C maximum, while NL27WZ86USG extends to 125°C.

Q: What does the -Q100H designation mean on 74LVC2G86DC-Q100H?

A: The -Q100H designation indicates AEC-Q100 automotive qualification. This part is suitable for automotive applications requiring automotive-grade component certification. All other electrical and package specifications remain identical to the standard 74LVC2G86DC,125.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, meeting standard environmental and regulatory requirements for commercial and industrial applications.

Q: Which substitute offers the best power efficiency?

A: The onsemi parts (NC7WZ86K8X and NL27WZ86USG) offer the lowest quiescent current at 1 µA, compared to 10 µA for Texas Instruments and 4 µA for Nexperia alternatives. For power-sensitive applications, NL27WZ86USG is preferred as it maintains the full -40°C ~ 125°C operating temperature range.
