74VHC86SJ XOR Logic IC Equivalent & Substitute Parts

Part Overview

The 74VHC86SJ is a 4-channel, 2-input XOR (Exclusive OR) logic integrated circuit manufactured by onsemi in a 14-SOP surface mount package. This part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity. The 74VHC86 series provides standard XOR logic functionality across the 2V to 5.5V supply voltage range, suitable for digital logic applications requiring exclusive OR operations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74VHC86SJ is determined by the following critical parameters:

• Logic Type: XOR (Exclusive OR) with 4 channels and 2 inputs per channel
• Supply Voltage Range: 2V ~ 5.5V minimum compatibility
• Output Drive Capability: 8mA high and low output current
• Propagation Delay: 8.8ns maximum at 5V, 50pF load
• Package Compatibility: 14-SOIC surface mount footprint
• Moisture Sensitivity: MSL 1 (Unlimited)

Substitute parts must maintain these electrical and mechanical specifications. The 74AHC86 series from Texas Instruments and NXP Semiconductors provides direct functional equivalence with identical logic configuration and compatible electrical characteristics. All identified substitutes operate within the specified voltage range and deliver equivalent propagation delay performance.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: SN74AHC86NSR (Texas Instruments)

The SN74AHC86NSR is the preferred direct substitute for the 74VHC86SJ. This part maintains identical electrical specifications including supply voltage range (2V ~ 5.5V), quiescent current (2 µA maximum), output drive capability (8mA), and propagation delay (8.8ns @ 5V, 50pF). The part is currently in active production status with ROHS3 compliance certification. The extended operating temperature range (-40°C ~ 125°C) provides additional thermal margin compared to the original part. Packaging is 14-SOIC with 0.209" width, matching the original footprint dimensions.

Secondary Recommendation: SN74AHC86DR (Texas Instruments)

The SN74AHC86DR provides equivalent electrical performance and active product status. This part shares identical logic specifications and electrical characteristics with the primary recommendation. The package footprint differs slightly (0.154" width versus 0.209"), requiring PCB layout verification before implementation. This part is suitable for new designs where footprint adjustment is feasible.

Alternative: 74AHC86D,118 (NXP Semiconductors)

The 74AHC86D,118 from NXP Semiconductors maintains the required XOR logic configuration with 4 channels and 2 inputs. This part is in active production status. Complete electrical parameter specifications are not provided in the available data; verification against design requirements is necessary before selection.

Frequently Asked Questions (FAQ)

Q: Can the SN74AHC86NSR directly replace the 74VHC86SJ without PCB modifications?

A: Yes. The SN74AHC86NSR maintains identical electrical specifications and the same 14-SOIC package footprint (0.209", 5.30mm width) as the original 74VHC86SJ. No PCB layout changes are required for direct substitution.

Q: What is the difference between the SN74AHC86NSR and SN74AHC86DR?

A: Both parts provide identical XOR logic functionality and electrical performance. The primary difference is packaging format: SN74AHC86NSR is supplied in Tape & Reel (TR) format, while SN74AHC86DR is supplied in Cut Tape (CT) & Digi-Reel format. The SN74AHC86DR package case is 14-SOIC (0.154", 3.90mm width), which differs from the original part's 0.209" width specification.

Q: Why is the 74VHC86SJ classified as obsolete?

A: The 74VHC86SJ is no longer in active production by onsemi. The 74AHC86 series from Texas Instruments and NXP Semiconductors provides superior product lifecycle status with active manufacturing and extended operating temperature ranges, making these alternatives more suitable for long-term design support.

Q: Are all substitute parts RoHS compliant?

A: The Texas Instruments parts (SN74AHC86NSR, SN74AHC86D, SN74AHC86DR) are ROHS3 compliant. RoHS compliance status for the NXP 74AHC86D,118 is not specified in the available data.

Q: What is the operating temperature difference between the original and substitute parts?

A: The 74VHC86SJ operates from -40°C to 85°C. The Texas Instruments 74AHC86 series substitutes operate from -40°C to 125°C, providing an additional 40°C of upper temperature margin. This extended range is beneficial for applications in elevated ambient conditions.

Q: Can I use the SN74AHC86D as a substitute?

A: The SN74AHC86D is discontinued at DiGi Electronics and should not be selected for new designs. The SN74AHC86NSR and SN74AHC86DR remain in active production and are preferred alternatives.
