SN74HC86PW XOR Logic IC Equivalent & Substitute Parts

Part Overview

The SN74HC86PW is a 4-channel, 2-input XOR (Exclusive OR) logic gate IC manufactured by Texas Instruments in a 14-TSSOP surface mount package. This part is currently discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing design support and procurement. The XOR logic function remains consistent across qualified substitutes, with variations in electrical performance characteristics and manufacturer certifications.

Substitute Part Grouping Explanation

Substitution eligibility for the SN74HC86PW is determined by the following criteria:

Primary Substitution Criteria:

Logic Type: XOR (Exclusive OR) with 4 channels and 2 inputs per channel
Package: 14-TSSOP surface mount configuration
Voltage Supply: 2V ~ 6V operating range
Mounting Type: Surface Mount
RoHS Compliance: ROHS3 Compliant

Secondary Performance Considerations:

Propagation Delay: Maximum 17ns to 26ns at 6V, 50pF load
Quiescent Current: 1µA to 20µA maximum
Output Current: 5.2mA high and low
Input Logic Levels: 0.5V ~ 1.8V (low), 1.5V ~ 4.2V (high)

Substitutes are grouped by manufacturer and product status. Direct functional equivalents maintain identical logic specifications. Extended temperature range variants (-55°C to 125°C) and automotive-qualified parts (AEC-Q100) provide enhanced performance margins but remain functionally compatible within the original operating window.

Engineering Selection Recommendations

Primary Recommendation: SN74HC86PWR (Texas Instruments) Active product status with identical electrical specifications to the original SN74HC86PW. Maintains the same propagation delay (17ns) and quiescent current (2µA). Recommended for direct replacement in existing designs without modification.

Extended Temperature Applications: 74HC86PW,118 or 74HC86T14-13 Both parts support -40°C to 125°C operating range, providing thermal margin beyond the original -40°C to 85°C specification. The 74HC86T14-13 offers superior propagation delay (15ns) but exhibits higher quiescent current (20µA). Select based on thermal requirements and power budget constraints.

Automotive Applications: 74HC86PW-Q100,118 AEC-Q100 qualified variant from Nexperia with extended temperature range (-40°C to 125°C). Suitable for automotive and mission-critical applications requiring formal qualification documentation.

Low Power Variant: MC74HC86ADTR2G (onsemi) Lowest quiescent current (1µA) with extended temperature range (-55°C to 125°C). Optimal for battery-powered or low-power applications where standby current is critical.

Avoid: NLV74HC86ADTR2G Obsolete product status. Highest propagation delay (26ns) among active alternatives. Use only if existing inventory must be consumed; transition to active substitutes for new designs.

Frequently Asked Questions (FAQ)

Q: Can I use 74HC86T14-13 as a direct replacement for SN74HC86PW? A: Yes. Both parts are 4-channel XOR gates in 14-TSSOP packages with 2V ~ 6V supply voltage. The 74HC86T14-13 offers faster propagation delay (15ns vs 17ns) but operates at higher quiescent current (20µA vs 2µA). Verify power budget compatibility before selection.

Q: What is the difference between 74HC86PW,118 and 74HC86PW-Q100,118? A: Both are Nexperia parts with identical electrical specifications. The -Q100 variant carries AEC-Q100 automotive qualification and formal reliability documentation. Select the -Q100 variant for automotive applications; standard variant for general industrial use.

Q: Is the 14-TSSOP package identical across all substitutes? A: Yes. All listed substitutes use the 14-TSSOP (0.173", 4.40mm Width) surface mount package. PCB footprints and reflow profiles are compatible across all parts.

Q: Why does MC74HC86ADTR2G have lower quiescent current? A: onsemi's manufacturing process achieves 1µA maximum quiescent current compared to 2µA for most competitors. This is a process advantage, not a functional difference. Both meet the XOR logic specification.

Q: Can I substitute the discontinued SN74HC86PW with NLV74HC86ADTR2G? A: Functionally yes, but not recommended. NLV74HC86ADTR2G is also obsolete and exhibits 26ns propagation delay versus 17ns for the original. Use active alternatives (SN74HC86PWR, 74HC86PW,118, or MC74HC86ADTR2G) for new designs.

Q: What does ROHS3 Compliant mean for substitution? A: All listed substitutes are ROHS3 compliant, indicating lead-free construction and compliance with hazardous substance restrictions. This ensures compatibility with modern manufacturing and environmental regulations.
