Key Parameters

Substitute Part Grouping Explanation

Substitution for the 74HC86N is determined by strict adherence to the following electrical and mechanical parameters:

Critical Substitution Parameters:

• Logic function: XOR (Exclusive OR) with 4 channels and 2 inputs per channel
• Voltage supply range: 2V ~ 6V minimum compatibility
• Output current capability: 5.2mA minimum for both high and low states
• Input logic levels: 0.5V ~ 1.8V (low) and 1.5V ~ 4.2V (high)
• Propagation delay: 20ns maximum @ 6V, 50pF load
• Package: 14-DIP through-hole mounting with 0.300" (7.62mm) pitch
• Base product series: 74HC86

All substitute parts listed maintain these core electrical specifications and physical package dimensions, ensuring direct functional and mechanical compatibility in existing circuit designs.

Engineering Selection Recommendations

SN74HC86N (Texas Instruments) is the primary substitute for new designs and ongoing applications. This part maintains active product status, ensuring long-term availability and supply chain stability. It meets ROHS3 compliance requirements and delivers superior propagation delay performance (17ns versus 20ns), providing additional timing margin in critical applications. The operating temperature range of -40°C ~ 85°C covers standard industrial and commercial environments.

CD74HC86E (Harris Corporation) provides functional equivalence with extended lower operating temperature capability (-55°C minimum), suitable for military or extreme cold-environment applications. However, this part carries obsolete status and RoHS non-compliance, limiting its use to legacy system maintenance where compliance requirements are not applicable.

74HC86N (NXP USA Inc.) remains the original reference part. ROHS3 compliance and standard operating temperature range (-40°C ~ 125°C) support both commercial and industrial applications. Obsolete status necessitates transition planning to active alternatives.

Frequently Asked Questions (FAQ)

Q: Can SN74HC86N directly replace 74HC86N in existing circuits? A: Yes. Both parts maintain identical electrical specifications for voltage supply, input/output logic levels, output current, and package dimensions. The SN74HC86N offers improved propagation delay (17ns vs 20ns), which is advantageous in timing-critical applications.

Q: What is the difference between 14-DIP and 14-PDIP packaging? A: Both designations refer to the same 14-pin dual-in-line package with 0.300" (7.62mm) pitch. The "P" in PDIP indicates plastic material. All three substitute parts use compatible through-hole mounting footprints.

Q: Is CD74HC86E suitable for new product designs? A: CD74HC86E is not recommended for new designs due to obsolete product status and RoHS non-compliance. It is appropriate only for replacement in existing legacy systems where compliance exemptions apply.

Q: What are the key electrical parameters that determine substitutability? A: The critical parameters are logic function (4-channel XOR), voltage supply range (2V ~ 6V), output current (5.2mA minimum), input logic thresholds, and propagation delay (20ns maximum). All listed substitutes meet these specifications.

Q: Does operating temperature range affect substitution decisions? A: Operating temperature range should be verified against application requirements. The SN74HC86N (-40°C ~ 85°C) covers standard industrial applications. The CD74HC86E (-55°C ~ 125°C) extends the lower limit for cold environments and upper limit for high-temperature applications.

Q: Are there compliance considerations for part selection? A: Yes. SN74HC86N and 74HC86N are ROHS3 compliant, meeting environmental regulations for new designs. CD74HC86E is RoHS non-compliant and should be used only in legacy systems where compliance exemptions are documented.
