74LVC86ADR2G Equivalent & Substitute Parts

Part Overview

The 74LVC86ADR2G is a 4-channel XOR (Exclusive OR) logic gate IC manufactured by onsemi, housed in a 14-SOIC surface mount package. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and procurement continuity. The 74LVC series operates across a supply voltage range of 1.2V to 3.6V, making it suitable for low-voltage digital logic applications requiring XOR gate functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74LVC86ADR2G is determined by the following critical parameters:

• Logic function: 4-channel, 2-input XOR gate
• Package type: 14-SOIC surface mount
• Supply voltage range compatibility
• Output drive capability (24mA minimum)
• Propagation delay performance
• Operating temperature range
• RoHS and regulatory compliance

The MC74LCX86DR2G qualifies as a functional substitute based on matching logic configuration, identical package footprint, compatible supply voltage operation, equivalent output drive specifications, and compliance certifications. Both components are manufactured by onsemi and maintain the same pinout and gate count.

Parameter Comparison

Engineering Selection Recommendations

The MC74LCX86DR2G is the primary substitute for the obsolete 74LVC86ADR2G. Both components maintain ROHS3 compliance and identical pinout configuration within the 14-SOIC package. The MC74LCX86DR2G offers active product status, ensuring continued availability and manufacturing support.

Key considerations for substitution:

• The MC74LCX86DR2G has a minimum supply voltage of 2V, compared to 1.2V for the 74LVC86ADR2G. Applications requiring operation below 2V are not compatible with this substitute.
• The MC74LCX86DR2G exhibits lower quiescent current (10 µA vs. 40 µA), providing improved power efficiency.
• Maximum operating temperature is reduced to 85°C for the MC74LCX86DR2G, compared to 125°C for the original part. Applications requiring operation above 85°C require alternative solutions.
• Propagation delay increases marginally to 6.5ns at 3.3V and 50pF load, remaining within acceptable performance parameters for most digital logic applications.

Frequently Asked Questions (FAQ)

Q: Can the MC74LCX86DR2G directly replace the 74LVC86ADR2G in all applications?

A: Direct replacement is possible for applications operating within the MC74LCX86DR2G specifications. The minimum supply voltage of 2V and maximum operating temperature of 85°C must be verified against your circuit requirements. Pinout and package footprint are identical, enabling direct PCB substitution.

Q: What is the difference between the 74LVC and 74LCX series?

A: Both series provide XOR gate logic with identical pinout and package options. The 74LCX series (represented by MC74LCX86DR2G) features lower quiescent current consumption and active product status, while the 74LVC series (74LVC86ADR2G) supports extended supply voltage range down to 1.2V and higher maximum operating temperature.

Q: Are there packaging differences between these parts?

A: Both the 74LVC86ADR2G and MC74LCX86DR2G are supplied in 14-SOIC surface mount packages with identical footprints. The MC74LCX86DR2G is available in Tape & Reel (TR) packaging format, suitable for automated assembly processes.

Q: What compliance certifications apply to both parts?

A: Both components are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8542.39.0001. Moisture sensitivity level is 1 (Unlimited) for both parts.

Q: How do propagation delays compare between the two parts?

A: The 74LVC86ADR2G specifies 6ns maximum propagation delay at 3.3V with 50pF load, while the MC74LCX86DR2G specifies 6.5ns under identical conditions. This 0.5ns difference is negligible for most digital logic applications and does not affect functional compatibility.
