Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74AC86SJX is determined by the following critical parameters:

• Logic function: XOR (Exclusive OR) with 4 channels and 2 inputs per channel
• Supply voltage compatibility: 2V ~ 6V operating range
• Output drive capability: 24mA minimum for both high and low states
• Propagation delay: 8.5ns maximum at 5V with 50pF load
• Operating temperature: -40°C ~ 85°C range
• Surface mount packaging: 14-SOIC configuration
• Quiescent current: 2 µA maximum

Substitute parts are grouped into two categories based on electrical parameter alignment:

Group 1 - Direct Electrical Equivalents: Parts with identical voltage supply range (2V ~ 6V), quiescent current (2 µA max), propagation delay (8.5ns), and temperature range (-40°C ~ 85°C). These parts are pin-compatible and functionally interchangeable.

Group 2 - Extended Parameter Substitutes: Parts with broader voltage supply range (1.5V ~ 5.5V) and higher quiescent current (4 µA max), but identical output drive capability and propagation delay specifications. These parts require verification of supply voltage compatibility in the target application.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: SN74AC86DR (Texas Instruments)

The SN74AC86DR is the preferred substitute for the 74AC86SJX. This part maintains identical electrical specifications including voltage supply range (2V ~ 6V), quiescent current (2 µA max), propagation delay (8.5ns), and operating temperature range (-40°C ~ 85°C). The SN74AC86DR carries Active product status, ensuring long-term availability and supply chain stability. It is ROHS3 compliant and carries REACH Unaffected certification. Packaging is 14-SOIC with 0.154" width, which is mechanically compatible with standard PCB layouts designed for 14-SOIC components.

Secondary Recommendation: SN74AC86NSR (Texas Instruments)

The SN74AC86NSR provides identical electrical performance to the main part with Active product status. This variant is supplied in Tape & Reel (TR) packaging format and maintains the same 14-SOIC footprint width (0.209", 5.30mm) as the original 74AC86SJX, offering direct mechanical compatibility. ROHS3 compliance and REACH Unaffected status apply.

Alternative Option: CD74AC86M96 (Texas Instruments)

The CD74AC86M96 is an Active product with ROHS3 compliance suitable for applications where extended temperature range (-55°C ~ 125°C) and broader voltage supply range (1.5V ~ 5.5V) provide design margin. Propagation delay is 10.8ns, which is acceptable for non-critical timing applications. Higher quiescent current (4 µA) should be evaluated for power-sensitive designs.

Not Recommended: CD74AC86M (Harris Corporation)

The CD74AC86M is obsolete and RoHS non-compliant, making it unsuitable for new designs or applications requiring regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can I use SN74AC86DR as a direct replacement for 74AC86SJX?

A: Yes. The SN74AC86DR is electrically and functionally equivalent. Both parts operate at 2V ~ 6V supply voltage, have 2 µA maximum quiescent current, 8.5ns propagation delay at 5V with 50pF load, and -40°C ~ 85°C operating temperature range. Pin configuration and logic function are identical. The primary difference is package width (0.154" vs 0.209"), which is not a functional concern for standard PCB layouts.

Q: What is the difference between the 14-SOIC packages listed (0.154" vs 0.209" width)?

A: Both are 14-pin SOIC packages with identical pin pitch and electrical connectivity. The width difference reflects manufacturing variations between suppliers. Both packages are mechanically compatible with standard 14-SOIC PCB footprints. The 0.209" width (74AC86SJX, SN74AC86NSR) is slightly wider than the 0.154" width (CD74AC86M, CD74AC86M96, SN74AC86D, SN74AC86DR). Modern PCB design software accommodates both variants.

Q: Why do CD74AC86M and CD74AC86M96 have different quiescent current and voltage specifications?

A: These parts represent different manufacturing processes and design generations within the 74AC86 family. CD74AC86M96 incorporates more recent process technology, resulting in lower quiescent current (4 µA vs unspecified for CD74AC86M) and broader voltage tolerance (1.5V ~ 5.5V). The CD74AC86M96 is the preferred variant between these two.

Q: Is propagation delay a critical factor in selecting a substitute?

A: Propagation delay becomes critical only in timing-sensitive applications. The main part and direct equivalents (SN74AC86DR, SN74AC86D, SN74AC86NSR) specify 8.5ns maximum delay. The CD74AC86M and CD74AC86M96 specify 10.8ns, which is acceptable for general logic applications but may exceed timing budgets in high-speed designs. Verify timing requirements before selecting CD74AC86M variants.

Q: What does "Active" product status mean for long-term availability?

A: Active status indicates the manufacturer continues production and supports the part through normal distribution channels. Parts with Active status (SN74AC86DR, CD74AC86M96, SN74AC86NSR) are suitable for new designs and offer predictable long-term availability. Obsolete or Discontinued parts may have limited stock and no future production commitments.

Q: Are all substitute parts ROHS3 compliant?

A: No. CD74AC86M is RoHS non-compliant. All Texas Instruments variants (CD74AC86M96, SN74AC86D, SN74AC86DR, SN74AC86NSR) are ROHS3 compliant. For applications requiring regulatory compliance or procurement policies mandating RoHS compliance, select only ROHS3-compliant alternatives.

Q: Can I use CD74AC86M96 in a design requiring -40°C ~ 85°C operation?

A: Yes. CD74AC86M96 operates across -55°C ~ 125°C, which encompasses the -40°C ~ 85°C range. However, verify that the broader voltage supply range (1.5V ~ 5.5V) and higher quiescent current (4 µA) are acceptable for your specific application requirements.
